1950-53: In their first season after Curly Lambeau's 31-year reign, the "New Packers" introduce their first identifying mark; the logo is also present on 1950 stock certificates. It changes colors over the four years, as the team experiments with several uniform combinations.
1954-61: Looking for a fresh look with new coach Lisle Blackbourn, the team unveils new uniforms and a new mark. The logo locates both Green Bay and Milwaukee on a Wisconsin silhouette. The passer wears No. 41, worn two decades earlier by both Arnie Herber and Clarke Hinkle.
1959-74: Sideline logo, worn on hats, shirts and jackets by coaches, equipment managers and trainers at both games and practice. Coincided with Vince Lombardi's first season, then retained by Phil Bengtson and Dan Devine.
1961-69: The primary logo during the Lombardi era, used on official Packers stationery and publications. The team won five world championships under the mark. Before the '69 season, after Lombardi's departure to Washington, team letterhead shifts to a helmet logo. The mark still sees use into the '70s, though.
1961-present: First and only helmet logo in team history, designed for Lombardi by equipment manager Dad Braisher and first applied to Packers headgear in 1961. After introducing the G, the team immediately won two world titles (1961-62), and five over the mark's first seven years. Borrowed by scores of schools, college and high school.
1993: Commemorative logo, worn on jersey during '93 season, signifying the team's 75th professional season, since its birth in 1919. Wearing logo, team earned first playoff berth in 11 years, kicking off string of six straight postseason trips.
2003: Patch team wore for first two home games of '03 to commemorate rededication of Lambeau Field, following three-year, $295-million renovation.
2006: Commemorative mark recognizing the 10th anniversary of the team's Super Bowl XXXI triumph over the New England Patriots.
2007: Emblem celebrating the 50th anniversary of venerable Lambeau Field, worn on home jerseys and painted in the end zones on the world-famous stadium grass.
