At first glance, it might not seem too odd, although if you look at it for another second, it's clearly not a picture like every other card in the set, but rather a drawing. And then you might notice the pre-printed signature in the bottom right hand corner of the card, which isn't on any other card. Then you could see the circular design at the top, and think, hey that looks familiar.
And that's because Gordon's Orioles Crown card uses the exact same picture that appeared on his 1959 Topps card. This has to be some sort of copyright infringement and I can't believe that Topps let it fly. But knowing their customer service department, it's possible they still haven't discovered it, but when they do, you can bet it will be replaced by a card of equal or greater value.
Gordon's card is far from the only one in the set that shows a player sporting another team's cap. There's plenty of players who only spent one season, or one game, with the O's almost thirty-forty seasons before the set was produced in 1991, so I understand that pictures of them in an Orioles uniform must have been hard to find, especially before the internet was widely used.
Just one thing though...
