From SportsLogos.Net, this is the earliest logo of the NFL’s Green Bay Packers. Dating from the league’s inaugural season of 1921, the logo refers to the club by it’s original name, the Acme Packers. NFL teams in the early days were often sponsored by companies and may have included company employees. That original Packer team included player/coach Curly Lambeau, and was heavy in players from Lambeau’s alma mater, Notre Dame. Some former Irish from that roster are Norm Barry, James Cook, Grover Malone, Frank Coughlin, Dave Hayes and Emmett Keefe.
