A set of Boston Celtics photo postcards circa 1956-57, the rookie season of NBA icon Bill Russell. Players featured in the set of 3.5x5.5 inch postcards include Bill Russell, Bob Cousy, Sam Jones, Red Auerbach, and Tom Heinsohn. Some of the cards have been signed by members of the team; Togo Pallazo, Jim Loscutoff, and Arnie Risen. These promo postcards were team-issued and are exceedingly rare. The Celtics would go on to win the 1957 NBA Championship, the team's first of 18 titles. This is a special opportunity for a Celtics fan or a fan of basketball history to add a unique item to their collection.
