Whenever I went to a baseball game as a kid, I always enjoyed the "free" plastic cup that came along with your drink. It was a great souvenir, plus you got 24 ounces of Coke! I have quite a few cups from the Oakland Coliseum, featuring Jose Canseco, Mark McGwire, and even Walt Weiss, but none of them ever featured Rickey.
I didn't get it from the stadium, but this "Collector's Series '87" cup from Yankee Stadium does feature Rickey, and probably came complete with a $10 beer. An artistic rendering of an action shot of Rickey is featured on one side of the cup, and in profile on the other.
I love the list of events that fans had to look forward to in 1987. I bet they had a sell-out crowd on the 4th of July for the Miami Sound Machine concert!
