The 64-card set issued in 1928 by the Exhibit Supply Company featured photographic images with a blue tint, a switch from the green-tinted cards of the prior year.  This example of Babe Ruth's card has been graded VG+ 3.5 by PSA, due primarily to edge and corner wear, as the image quality is quite strong, picturing Ruth staring upward at a fly ball that just came off his prodigious bat.  An outstanding card of the hobby's most popular and valuable subject.
