This is an old English “B” script logo that was in use in the early days of the AFL’s Buffalo Bills. It was only seen on baseball style caps that the coaches wore, and was modeled after the script “D” that baseball’s Detroit Tigers used. Bills’ original owner and founder Ralph Wilson Jr. was a Detroit native and even incorporated the Lions’ blue and silver color scheme on the Bills’ original uniforms. By 1962, their third season of existence, the Bills switched to the now more familiar blue, white and red with the red standing buffalo helmet logo.
