1968 Topps 3-D Test Set: The Brooklyn Summer When Cards Popped Off the Paper

Picture New York in the late 1960s. Corner drugstores, spinning postcard racks, and a plain white pack for a nickel that promised something strange called “3-D.” Kids cracked them open, tilted them under the fluorescent lights, and watched Roberto Clemente and friends jump forward like they were stepping out of the cardboard. Then the cards curled, cracked, and disappeared into shoeboxes. A myth was born, and it has never really died.

The 1968 Topps 3-D test set is one of the most fascinating, most argued-about, and most sought-after test issues in the entire hobby. Here is everything you need to know about it.

What This Test Issue Actually Was

The 1968 Topps 3-D set was a tiny test run of just 12 unnumbered cards, produced on lenticular plastic. Each card measures approximately 2¼ x 3½ inches, a quarter-inch narrower than a standard trading card, with rounded corners and completely blank backs. The lenticular surface uses intentionally blurred backgrounds to make the player photograph pop forward when you tilt the card, creating a genuine sense of depth with no glasses required.

The printer behind the cards operated under two names you will see in hobby references: Visual Panographics (the New York mailing address on stamped-back copies) and XOGRAPh (the operational company based in the Dallas-Fort Worth area). They are the same outfit, and that Dallas connection becomes important later.

The Brooklyn Distribution Story: What the Hobby Says and What the Evidence Shows

Hobby lore holds that the cards appeared briefly in a handful of Brooklyn candy stores in the summer of 1968. The packs were two cards for five cents, came with a stick of gum, and each pack included a small fold-up easel so you could stand the card on your desk. Packs were sold in display boxes of 12, and a complete box today is considered one of the rarest surviving pieces of the entire set.

Here is where the story gets complicated. Veteran dealer Bill Goodwin estimates that only a few thousand cards were released in total. More tellingly, nearly every known example on the secondary market can be traced back to someone who worked for either Topps or XOGRAPh, not to a kid who bought a pack at the corner store. The Brooklyn candy store origin is part of the legend, but provenance on most surviving copies tells a different story. That ambiguity is part of what makes this set endlessly interesting and endlessly debated.

And why did Topps not roll it out further? The answer is straightforward. As Goodwin explained: “They were just too expensive for Topps to continue.” The experiment generated interest but not enough to justify the production cost. Topps got its answer and moved on, leaving behind one of the hobby’s great what-ifs.

Complete Checklist

The official 12-card checklist, in alphabetical order. Two of the twelve are Hall of Famers:

• Roberto Clemente, Pittsburgh Pirates
• Willie Davis, Los Angeles Dodgers
• Ron Fairly, Los Angeles Dodgers
• Curt Flood, St. Louis Cardinals
• Jim Lonborg, Boston Red Sox
• Jim Maloney, Cincinnati Reds
• Tony Pérez, Cincinnati Reds
• Boog Powell, Baltimore Orioles
• Bill Robinson, New York Yankees
• Rusty Staub, Houston Astros
• Mel Stottlemyre, New York Yankees
• Ron Swoboda, New York Mets

Clemente is the anchor of the set by a wide margin. His 3-D card is widely regarded as his most visually spectacular issue and significantly scarcer by population than his 1955 Topps rookie. Worth noting: the 1955 Topps remains his officially recognized rookie card and carries all the prestige that designation brings, so the two cards occupy different parts of the market. The 3-D is the rarer object; the rookie is the more universally known trophy. Tony Pérez is the only other Hall of Famer among the 12 confirmed subjects, though the Brooks Robinson prototype (more on that below) pushes the Hall of Fame count to three if you include proofs.

If you are checking a shoebox find, confirm the player and team against this list before getting too excited.

Variations: More Complicated Than They Look

The official checklist says 12 cards. The real collector count is considerably higher. A 2007 Sports Collectors Digest article by Keith Olbermann documented that five of the 12 subjects have variations, mostly involving slightly different photo cropping: Ron Fairly, Boog Powell, Jim Maloney, Rusty Staub, and Curt Flood. Factor in the stamped-back copies, ink color variants, and proof material, and the set expands to over 50 distinct items by some counts.

For most collectors, the base 12 is the target. But knowing the variations exist matters every time you are evaluating a purchase.

The XOGRAPh Stamped Backs

Most surviving 1968 Topps 3-D cards have completely blank backs. A small number, believed to be among the earliest produced, carry an ink stamp in either red or black that reads:

“This is an experimental XOGRAPH card produced as a limited edition. Not for public circulation or distribution. Not for resale. To be returned to: Visual Panographics, Inc., 488 Madison Avenue, New York, New York.”

Clearly nobody returned them. These stamped-back examples are notably scarcer than standard blank-back copies and carry a meaningful premium. The ink color (red vs. black stamp) is an additional detail that completionist collectors track. If you find one with a stamp on the back, that is a feature, not a flaw.

The Prototype Cards: An Even Deeper Rabbit Hole

Beyond the official 12, a small number of prototype cards have surfaced over the decades. These predate the final test issue and carry PSA Authentic designations rather than numeric grades. Known prototypes include:

• A Brooks Robinson prototype in a 1967 Topps-style design with only “Orioles” at the top and no player name. One of only three confirmed in PSA holders, with a known sale of $20,000 at Huggins and Scott, and a six-figure estimate at Heritage Auctions in 2025.
• Proof sheets with unissued subjects including Tommy Davis, John O’Donoghue, and Rick Monday, appearing without player or team name text.
• Prototypes featuring international soccer subjects, confirming XOGRAPh was testing the format well beyond American baseball.
• Square-cornered proofs have also been documented, worth keeping in mind before applying the rounded-corner authentication rule to prototype material.

In 2015, an uncut sheet featuring Clemente alongside two unreleased subjects sold at Goodwin and Co. for over $50,000. The sheet came from the Benanti Collection, named after a Dallas man whose father had worked at XOGRAPh.

Why Survivors Have Battle Scars

Lenticular plastic looks incredible but it is unforgiving to preserve. These cards curl and craze across the surface as they age, and edges frequently develop fine micro-fractures that spread over time. Condition is half the challenge and most of the value. A flat, crack-free example at any meaningful grade is genuinely rare. High-grade Clementes are especially scarce: PSA has graded just 86 of them across all grades, and gem-mint examples are essentially nonexistent.

How to Spot Authentic Cards vs Reproductions

The 1968 Topps 3-D has been widely reproduced. Here is what separates real from fake on the base 12 cards:

• Size: authentic cards measure 2¼ inches wide, a quarter-inch narrower than standard. A card at exactly 2.5 inches is not a 1968 original.
• Corners: genuine base cards have rounded corners. Square corners on a claimed base-set card are a red flag (note: square-cornered proofs do exist, but only in the prototype tier).
• Back: authentic cards have blank backs or an XOGRAPh ink stamp in red or black. Any other printing on the back rules it out as a 1968 original.
• Depth effect: backgrounds are intentionally blurred with the player sharp in the foreground. Reproductions miss the graduated quality of the blur; fakes tend to look uniform across the entire background rather than graduated by depth.
• Surface texture: tilt the card under direct light and look for natural lenticular ribbing across the surface. A flat laminated feel means reproduction.
• Grading: for any serious purchase, buy only PSA or BGS graded examples. The population on this set is small enough that the authentication fee is money well spent.

The Legacy: From Brooklyn to Your Kellogg’s Box to Modern Refractors

Here is the part of this story that most posts miss entirely. The 1968 Topps 3-D test set did not just vanish. The same technology, from essentially the same company, powered one of the most beloved card lines of the 1970s and early 1980s.

XOGRAPh went on to produce the Kellogg’s 3-D baseball card sets from 1970 through 1983, a 14-year run distributed inside cereal boxes across America. Millions of kids grew up with those cards without ever knowing they were holding the direct descendant of the 1968 Brooklyn experiment. Five players from the original 1968 Topps 3-D checklist, including Clemente, Flood, Lonborg, Maloney, and Stottlemyre, also appeared in the 1970 Kellogg’s set, making the genealogy explicit.

The same lenticular printing technique resurfaced in the 1980s with Sportflics, which used motion-shift effects to show multiple player images on a single card. Topps itself returned to the format with the 1995 Topps D3 insert set. And if you want to draw the line all the way to today, the holographic refractors, chromium parallels, and prismatic foils in every modern high-end product owe a creative debt to what XOGRAPh pulled off in that Brooklyn test run.

Topps formally acknowledged the lineage with a 2012 Topps Archives insert set that recreated elements of the 1968 3-D design with contemporary players. If you want the aesthetic without the four-figure price tag, that Archives run is worth tracking down.

Is This Set Worth Collecting?

That depends on your budget and your goals, but go in with realistic expectations on price. Even a rank-and-file player from the base 12, think Bill Robinson or Ron Swoboda in mid grade, is widely reported to cost $1,000 or more. Higher-demand names like Boog Powell and Rusty Staub in comparable grades command several thousand dollars. The Clemente is a different universe entirely: graded mid-grade copies reach serious four-figure territory, and high-grade examples operate as genuine trophy pieces for advanced vintage collectors.

PSA’s auction records show over 210 tracked sales with combined realized values pushing toward a million dollars. This is an actively traded, deeply liquid corner of the vintage market. For vintage purists with the budget, the 1968 Topps 3-D is one of the most visually striking cards ever made and one of the great conversation starters in any serious collection.
