Interesting letter/advertisement signed by HOF member Max Carey. The letter describes his belief that baseball is the "GREATEST GAME in the history of the world" and how proud and honored he was able to be apart of it during his career. He also goes on to try and sell his book, "Baseball Secrets Revealed" and recommends that you shouldn't loan it to anyone, presumably so your friends will buy their own. Also included is a typed sheet of his career highlights with the name "Max" written in pencil.
