If you are a student of the game and a lover of its history then you no doubt know who this fellow is. Featured above is a vintage 1923 original Charles Conlon photograph of famed catcher Moe Berg. Best yet, he is seen in a Brooklyn Robins/Dodgers uniform, and according to the auction house may be the only known photograph of him in a Brooklyn uni. It recently sold this past weekend at an RMY Auction for $383.
As you may know, Berg was not only regarded as the smartest (i.e. brainiest) ballplayer there ever was, but it was also revealed that he worked undercover as a spy for the American Office of Strategic Services (a precursor to the CIA) during and after WWII.
