Original World War II-era color 31 x 41 propaganda poster featuring an image of Hall of Famer Johnny Mize at bat issued by the 'Inland' division of General Motors to encourage wartime production, with the large slogan at the top, "Let's Rock 'em and Sock 'em," and text below: "Hit and Run, Every Day…Till Victory's Won, The Inland Way for U.S.A." Rolled and in very good to fine condition, with light creasing, and some short tears and minor loss to the borders. Rarely encountered, this is one of only a few known surviving examples.
