Slightly O/T - What Is This Card?
 

I know this is postwar, but have struck out asking the shiney stuff collectors. I got this as a gift back when I was working on Oriole Park in 1991 or 92 and it was obviously a pro for a card set, but I've never come across any others from this set. Anyone ever see one like this or know anything about this set?
