The art on this 1970 Vintage Buffalo Bills Sweatshirt has been custom produced by Vintage Brand. The Bills won consecutive AFL Championships in 1964 and 1965, the only major professional sports championships from a team representing Buffalo. The Buffalo Bills original colors were Honolulu blue, silver and white, and the helmets were silver with no striping. There was no logo on the helmet, which displayed the players' numbers on each side. In 1962, the standing red bison was designated as the logo and took its place on a white helmet. In 1962, the team's colors also changed to red, white, and blue. The team switched to blue jerseys with red and white shoulder stripes similar to those worn by the Buffalo Bison's AHL hockey team of the same era. In 1973, the the standing bison logo was replaced by a blue charging one with a red slanting stripe streaming from its horn.
