This 1968 color poster set is not an "insert" but was issued separately with a piece of gum and in its own wrapper. Each poster cost five cents and Mickey Mantle was the featured player on the box. The posters are numbered at the lower left and the player's name and team appear in a large star. The poster was folded six times to fit into the package, so fold lines are a factor in grading. Each poster measures 9 3/4" by 18 1/8".
