Originally issued in one-card penny packs and billed by Topps as "A gimmick penny baseball series," these cards call to mind the 1911 Mecca "Double Folder" cards which featured two players. Unfolded, these cards measure 2 1/16" x 4 7/8" and depict illustrated players set against a stadium background. When folded, the player image on the reverse becomes the front, sharing the same legs and feet of the player image on the front. When placed side-by-side in numerical order, the card backgrounds form a single continuous scene.

This offering is the Henry Aaron/Ray Herbert issue in a wonderfully high grade. Aaron is the main image, with centering just a hair south on the canvas. Edges are crisp, and corners are sharp, with only a faint bit of staining at the bottom border. The Herbert side has some very faint foxing, mostly on the text half, but is also beautifully clean with brilliant colors. An excellent opportunity to acquire a difficult early Topps issue.

SGC has only ever graded 31 total unperforated examples of this Aaron/Herbert Double Header, with only 9 receiving a higher grade than the NM+ 7.5 offered here.
