Among the most rare of all the late 1950s regional issues is the eight-card "test" issue which preceeded the 1958 Hires Root Beer set. The "test" cards are sepia-toned photos on a yellow or orange background which originally contained tabs at the bottom with offers to join the Hires Baseball Club. Today the cards are extraordinarily scarce with or without the tabs attached. Strong example featuring Hall of Famer Willie Mays (without the tab) graded EX 5 by PSA with strong image quality but moderate corner and edge wear.
