Two hard to find high-number uncut proof sheets featuring Yankees, Dodgers, Phillies, and Floods. Curt Flood that is. Both blank back “progressives” display the same set of players, though one is an earlier specimen as evidenced by its inclusion of only last names and lacking full color. Thirty-three cards per sheet. Light, even edge and corner wear along with minor discoloration of the lower portions of have resulted in the pair grading EX.
