The Buffalo Bills pennants from the 1960's and early 1970s are usually not dated, but there are some clues to their dates.  For the first season (1960), the Bills colors were blue and silver. The original Bills logo was an oval with 2 players and 2 buffaloes in it it. Later this logo was revised to a single player and a buffalo. The "standing buffalo" helmet was used through the rest of the 1960's and until 1973. Also the Bills originally started in the AFL, and later the NFL after the leagues merged (1969).  Three pennants of note from the 60's are the photo pennants honoring the team's  AFL Championship teams.

All Pennants approximately 12" x 30", except where noted.
