Baer wasn't Jewish, though he wore the star on the trunks because he was a quarter Jewish from his father's side. He was raised Catholic. Could replace the spot with Bob Pastor, one of the top three heavyweights between 1938-1942.
Briscoe wasn't Jewish. Mike Weaver wore a star of David Pendant wasn't Jewish either. Ray Arcel who was Jewish said Baer wasnt.
The funny quote on Arcel when he was asked if Baer was Jewish was, "He ain't a Jew, I've seen him in the shower."
