Awesome card Jon. You must have an amazing Canseco collection.;)

An old friend of the variation thread was very gracious to send me a scan of his 58 Topps Dave Jolly print error card that fits in next to the 58 Enos Slaughter print error, now it looks like the card below Jolly, #189 George Susce, is probably affected with the missing black ink print flaw.

Great info Cliff

Looks like a 90 Topps Frank Thomas situation. Great find!

This one is not pre-1980, but I just discovered this in my McGwire box over the weekend. I know for a fact that it is reoccurring because I have 2 of these that are identical. I was just wondering if anybody knew how scarce it is, if at all. I do know that I searched Ebay and COMC and could not find another. Here it is.

Not a print variation/error. But some kind of inventory label that got on the sheet before cutting, collating and packaging.

That's a good one sb

I've never seen anything like that before. It's one of the cooler cards I've seen.

Topps variations...
 

I found a few variants from my Topps collection...

A cool 58 Nellie Fox missing the yellow ink...

A 74 Stargell also missing yellow ink...

And a 94 Stadium Club Ryan no foil...

Another variant...
 

I also have a blank front 1970-71 Maravich rookie...found in a small collection I picked up a few years ago...
