The 32-card set was exclusively comprised of members of the Pacific Coast League's Oakland Oaks. And while Charlie Dressen would make a name for himself as manager of Brooklyn's Boys of Summer from 1951-53, the best know acorn on the team was a young infielder named Billy Martin.
Only available in the Bay Area, this is a fairly rare set but not a particularly expensive one. Distributed in loaves of Remar bread, samples can be found for under $10.
What a treat to go along with that peanut butter and jelly sandwich.
