1949-1952 Chicago Bears Autographed Official NFL Football, Extremely Rare

Here is an official NFL white football autographed by the Chicago Bears. White footballs were used for night games at this time for better visability of the ball. I was able to pinpoint the time period of the ball by researching the autographs on the ball. Bulldog Turner was easy to recognize, so I knew the team was the Bears.By researching the other names I was able to date the ball between 1949 and 1952. Bert Bell was the commissioner at the time. The ball was made by Wilson, and distributed to the NFL teams through the Thorp Sporting Goods Company of New York.I found this extremely rare ball at an antique store in a suburb of Chicago. Price....$19.99!
