This incredible 1958-59 Boston Celtics Team Autographed Poster was offered in Sotheby’s Important Baseball Cards and Sports Memorabilia auction in June 2005. It included all 11 players from the NBA Champion team, plus coach Red Auerbach and trainer Buddy LeRoux.
The 1958-59 Celtics swept the Minneapolis Lakers in the 1959 NBA Finals, then known as the NBA World Championship Series, and kicked off the Celtics streak of eight straight titles between 1959 and 1966.
The Near mint to mint-conditioned image was described as 20” x 24” in size and with flawless signatures by Bill Russell, Bob Cousy, Sam Jones, and Bill Sharman. It came with an LOA from PSA/DNA.
I found the following example of the same picture, but without the text beneath the image showing, on eBay (June 2004) for just under $3k, accompanied by an LOA from Beckett. The autographs are in slightly different locations for each player, so it’s a unique piece.
