1964 Philadelphia football card of former Green Bay Packer defensive end Willie Davis. With the conference championship games coming up this weekend, this is a great card to feature, since Davis played in 6 NFL championship games in his Packer career, with the Pack winning 5 of them. Davis played 12 seasons in the NFL, starting in 1956 with the Cleveland Browns. He was traded to Green Bay in 1960, becoming a stalwart on the Packer defense that won those 5 titles, which also included the first two Super Bowls. Davis never missed a game in those 12 seasons, and was a five time Pro Bowler. He was elected to the Pro Football Hall of Fame in 1981.
