Why would I have Japanese baseball postcards? It's only because my neighbor had a Japanese pen pal when he was a boy. Otherwise, these would be hard to come by.
Shigeru Sugishita was one of the premier pitchers in Japanese professional baseball in the 1950s. This picture is circa 1951, when he was pitching for the Dragons. He beat out Wally Yonamine for Central League MVP in 1954 (a very big deal!) and was presented with the Sawamura Award three times. Sugishita was inducted into to the Hall of Fame in 1958.
