I was looking through some old Calbee cards today (looking to see what I had in the way of Hiromitsu Kadota cards for the next Career Home Run Leader post) and I came across this card of Tsutomu Wakamatsu from 1979:
1979 Calbee was a little odd. Calbee produced over 400 cards that year in about 12 different sets. There was the "regular" set; sets for the "best" players (according to some sort of contest) for April, May, July, August and October; sets for the April-June "stars" for both the Central and Pacific leagues; a "Title holders" set; a set for the the Central League Champion Carp; a different set for the Nippon Series champion Carp and a set for the Nippon Series between the Carp and Buffaloes itself.
The Wakamatsu card is from the "May Best" series. It is card number 15, indicating that he came in 15th in the contest (Shigeru Kobayashi came in first).
