One of the most fascinating figures in baseball history - mostly for his career off the diamond - Moe Berg was actually a spy after (and some believe, during) his Major League career. This lot is all about the journeyman player and includes: Three signed checks; French library card handwritten "Monsieur Morris Berg"; January 20, 1941, admission pass for The White House; Princeton yearbooks from 1921-1925; June 16, 1923 Yale vs. Princeton baseball program; books detailing his history, and more.
