The copper top battery entered the baseball card world in 1993. Their stay didn't last very long, just one year. Their batteries should last longer than that!
The Duracell Power Players set consists of two 24-player series. You got your cards by mailing in proofs of purchase. There is one Cub in each of the two series.
Andre Dawson is #3 in the first series, while...
...Ryne Sandberg is the 13th card of the second series.
Like most of this type of set, they just had a players' license, meaning the logos have been removed.
