The 1988 Topps Mark McGwire “White Triangle” card (#3) is one of those classic late-80s oddities that perfectly captures the quirks of the junk wax era.

This card comes from the “’87 Record Breakers” subset, celebrating Mark McGwire’s historic rookie home run total. On early printings, a small white triangle shape appears near his left foot—something that wasn’t supposed to be there.

What actually happened

The “white triangle” is essentially a printing/editing mistake. Topps quickly corrected it by filling the area in with red on later print runs, creating two versions:

• Error version: white triangle visible

• Corrected version: no triangle (filled in properly)

There’s even some hobby lore that Topps may have been trying to “fix” the look of McGwire’s foot in the image, but ended up creating a more noticeable flaw instead.

Hobby significance

This card is:

• One of the most well-known variations in the 1988 Topps set

• A classic example of how minor print defects became “errors” collectors chased in the 80s

• Often one of the first “error cards” collectors remember pulling as kids

Value reality (important)

Despite the attention it gets, it’s not rare:

• The set was massively overproduced

• Both versions are fairly common

• Typically a low-dollar card unless in pristine graded condition

Why it still matters

Even without big value, the McGwire white triangle card sticks around because it has:

• A clear, easy-to-spot variation

• A connection to one of baseball’s biggest sluggers

• That nostalgic “pack fresh discovery” feel from the late 80s

It’s less about rarity—and more about the story and the era it represents.
