Primarily cribbing images from the secondary "action" photos on their 1955 baseball cards, Topps Double Headers mimicked the old Mecca Double Folders of 1911.  Issued solely in one cent packs, these colorful, metamorphic cards remain a treat today. Hall-of-Famer Al Kaline, seen here with the typical centering and cut usually found with this issue, shares the card with Corky Valentine.  The fold lines are intact and unstressed, while the colors front and back remain bright; an errant print line can be seen on the reverse of this EX specimen.
