In 1975, a series of instructional aids posters featuring illustrations of six MLB stars, all of whom would eventually be inducted into the Baseball Hall of Fame, was released. Seldom seen together in one group, the large and colorful posters each measure 13” by 18” and spotlight top baseball talent including Mickey Mantle, Roberto Clemente, Frank Robinson, Tom Seaver and Hank Aaron. Only the Mantle example is shown in horizontal format. The player’s biography appears on the reverse of each poster. The posters were produced by a company out of Mankato, Minnesota and all appear in good condition with tiny pinholes in the corners.
