The idea behind Phantom Cardboard is the creation of cards that are modeled after vintage trading cards that didn't actually exist. Well, when doing some scrolling recently on eBay I happen to come across the card pictured above. Not only was an Ahmad Rashad card made for the preseason game in 1990 that he suited up for the Sixers, but it was made by the exact same card set I was looking to emulate -- the 1990-91 Skybox set.
It wasn't part of their regular set, it was a part of special broadcasters set Skybox put together. I searched out and found that there's a total of four cards to this set. Along with Ahmad there is Julie Moran, Bob Costas and Pat Riley (although I could only find images for Rashad and Moran).
Whoopsie. Oh well.
