The 1985 Topps 3-D card, with Rickey in his A's uniform, is one of my favorite cards in my collection. I really like the way the 3-D effect actually makes him jump off of the card! The cards are blank backed (except for a few pieces of double-stick tape), and are approximately 4"x6" large.
The card above is from the 1985 Topps 3-D set, and is number 10 of 30. Rickey was actually traded to the Yankees before the 1985 season began, but he didn't show up as a Yankee until the 1986 Topps 3-D set, where he's number 11 of 30.
