Wrong back Topps card, 2 different sports?
 

1991 Topps card with Baseball front and 1990 Football back, is this really possible?

Yes. Not sure if they were pack inserted or walked out the back door, but they are real.

1991
 

Another addition to the 5000 + master CL for the 1991 set. ;)

Here is my Juan "Gon" card with a Terry Taylor back......since SGC does designate this variety of 91 Topps, a set builder could indeed complete a registry set with all NFL backs.

Darn it!!!!!! I am never done with this set!!!!!!!

1991
 

No, no Sean. Go for it

I agree Sean you need to go for it. Just to help I have a few 100 blank front 90 Topps football I would send you so you could just draw whatever front you want on them.;)

I think back in the day one of my NJ Dealer friends had 1979 Baseball with 78 Football Backs

Those would be cool to have 1 of. I have wrong backs with 79 Topps fronts and 78 Topps backs. Both sides are baseball though.

I picked up a Hensley Meulens like this several years ago.

You will also have to keep your eye out for those double front cards (image printed on both sides of the card).

Does anyone know how these BB fronts/FB backs were distributed? IE wax, rack, vending, box set?

I don't know if they distributed cut card cases in '91 but that is were I have found a ton of printing flaws and wrong backs etc.

I would agree that a cut card case would be a likely source of cards like this.

These are print waste that was removed from the facility, NOT inserted in any packaging type.

They have appeared with frequency on ebay over the last few years.

There are no known variations in player combos. 528 cards for 1990 Topps football means that there are 264 1991 Topps baseball subjects who are not available with the football back. aka 4 132 card sheet from 1991 MLB were printed with 4 132 card sheets of 1990 NFL.

There goes Dyan again, clouding the issue with facts :)

I wasn't saying they were. But if you saying that blank and wrong backs can't be found in cut card case; you are dead wrong.

Not what I'm saying at all. I've pulled both out of junk Topps wax. However, certain wrong backs/blank fronts were heavily backdoored: 1988-1991 Topps blank fronts and 1987-1989 Topps and 1990 Bowman wrong backs, for example, are always available for sale in large quantities.

I'm saying these 1991 BB/1990 FB cards were not packed out, but backdoored in sheet form. I can recall word of this in 1991. There have been many for sale recently as sheets have been cut up and sold as singles.

I have a 1990 Bo Jackson baseball with a football back.
