OK, I can "identify" this in some regard. Here's the backstory.
My dad obtained this in 1989 when I started watching Redskins/WFT/Commanders games, he got it out of a ad in Sports Collector's Digest where Roy Jefferson offered to send out a signed card for a $5 donation. As for the exact release date, who really knows, but it was advertisted in 1989.
What I'm not sure of is how to catalog this or if it should be cataloged in TCDB. It is very much a card, although a bit oversized (a little smaller than a vintage postcard, 4.5 in on the long side, 2.75 in on the short). I'm not sure if there are any unsigned examples, I believe this was intended to be distributed with the autograph. Maybe list with a signed and unsigned variation?
What do others here think?
