Rare 1955 Hall of Fame Induction poster was only posted on the streets of Cooperstown (likely hung at Doubleday Field) for the critical entrance of Joe DiMaggio, Home Run Baker, Gabby Hartnett, Ted Lyons, Dazzy Vance, and Ray Schalk. Interestingly, the M.C. was sportswriter Shirley Povich, father of Maury. Mint signed twice by Joe DiMaggio. Signatures obtained in person by Barry Halper, from whose collection this derives. Poster is 22x14" and has creases and pinholes, but find another!
