The first Cub to show up as a Baseball Hero was Ryne Sandberg in 2005. But the set had been changed to a stand-alone set of 100 base cards and another 100 short-prints. Ryno had five cards in the set, numbers 66-70. Each card highlights a different event in Sandberg's career. My only gripe is that the picture on the card doesn't always match with the event on the back.
#66: 1984 - The Sandberg Game....but the picture on the front is from 1997 (that is the Jackie Robinson 50th anniversary on his sleeve)
#67: 1984 - Wins NL MVP...and another picture from 1997
#68: 1990 - Sets Record For Second Baseman
#69: 1997 - Sets HR Record in 1997, but this card doesn't have a picture from 1997. Go figure!
#70, a nice looking end to the run.
Upper Deck brought Baseball Heroes back one last time in 2008. I'll have those Cubs tomorrow.
