This trading card is a part of DC's 1993 "Cosmic Teams" cardset. This set was interesting in that it was almost entirely focused on teams, as the name implied. Since Hawkman was a member of the then recently released from Limbo Justice Society of America (before Zero Hour where most of the team was killed or otherwise weirded up), he is featured on his own card, as well as on the Justice Society's triptych, which I will post another time. Note that he is called out as the Golden Age Hawkman.
The card art is by none other than Mike Parobeck, who draws a pretty sweet pair of Hawks, I must admit! Maybe I can make a banner ouf of it or something.
