Before the signature mustache, Thurman Munson was a hot catching prospect with the Yankees. This early 1970s promotional photo shows off the future MVP's boyish charm and features his signature in aqua-colored felt-tip pen. The signature rates 8/10 and the photo bears a slight crease at the upper-left corner, otherwise EX. Munson's first full season was in 1970, when he batted .302 and merited American League Rookie of the Year honors. This photo easily could have been snapped at that time. 4"x4.75"
