1949 Bowman #147
This vintage rookie card--and its weird-looking fake cap--marked Elmer's second stop in the majors. He debuted with Boston in 1945, but moved to Pittsburgh by the time Bowman resumed post-war card production in 1948. (Career stats at Baseball-Reference.com.)
More critical to today's set profile, Singleton spent 20 years in the minor leagues, including 12 in the Pacific Coast League. Along the way, he picked up the colorful nickname "Smoky." Pitchers often get called "smoke" if they can bring the heat, but I suspect Elmer got it for some other reason. (Not sure why 1949 Bowman went with "Bert," since it's actually his first name.)
Value: Cards from this obscure, 18-card set shows up every so often on eBay. I probably overpaid on this #5 at $15, but sometimes rarity trumps financial pragmatism.
Fakes / reprints: It'd be easy enough to reprint one of these black-and-white cards, but doesn't seem worth the trouble.
