Allie helped New York win an unprecedented 5 straight World Series from 1949 to 1953. Could a team be that dominant in today's free agent era? Since 1973, the Yankees do lead baseball with 7 titles--but that's just 1 more than Reynolds picked up in less than a decade.
The 1975 convention took place in Des Moines, Iowa, hence the Sheraton underwriting. (Perhaps Great Plains SCA used the hotel itself for their show space.)
Aside from his pitching accomplishments, Allie Reynolds was also the son of a preacher man. Alert Dusty Springfield!
Value: This #5 cost $5 on eBay. Its bigger names (Feller, Maris, Berra) cost $10 or more.
Fakes / reprints: Haven't seen any fakes in the market and assume the market's too small to be worthwhile.
