Is it possible that the set is larger than we thought?
I was screwing around on google and found these from Baseball Digest:
Oct 1979
Apr 1980
Jul 1980
Mar 1982
The pictured statues match the ones in the Signature Miniatures set.
I also found this Sporting News clip (google won't allow you to see whole article)
