Great stuff and information. Here are a pair of Joe Louis stamps:
This one says he's 21 years old. Louis was born May 13, 1914, so he would have been 21 until May 13, 1936. The last of the three bouts mentioned took place on 9/24/35.
This one mentions his loss to Max Schmeling. That was June 19, 1936.
This DiMaggio mentions his first month with the Yankees. That would be 1936.
PSA grade's them:
