Logo of the Baltimore Colts’ football team that played in the All America Football Conference from 1947 until 1949, then joined the NFL in 1950. This original Colts franchise folded in 1950, however, and another Colts team was born in 1953 from remnants of an NFL team that had been based in Dallas. That franchise is the one that now plays in Indianapolis. Despite being totally different entities, both Colt franchises had logos that were almost identical. The AAFC Colts, in their short existence, boasted 3 future Hall of Famers on their roster – Art Donovan, George Blanda and Y.A. Tittle.
