No fewer than 33 greats signed this copy of Arthur Daley's book "Pro Football's Hall of Fame," which features bios of many football greats. Three of the famed four horsemen signed (missing Crowley), while others represented include Halas, Johnny Blood, Nagurski and Pete Rozelle (2). Six of the original 12 signed (five were dead). In all, the signatures average 9/10 out of 10 and are mostly in red. The Book is EX overall; a second copy also comes with the signed one, with an inscription from Dick McCann, the Hall of Fame director at the time of this 1963 publication.
