Long thought to be strip cards, recent discoveries identify the W555 issue as coming from the side of a candy box fashioned into the form of a pinhole camera, with each of the cards designed to give the impression of being a "photo." This image of Christy Mathewson is taken from the famous photo that yielded the T206 "Dark Cap" pose, (a Type 3 example of the photo is featured elsewhere in this auction).  Graded PR 1 by PSA, due to creasing and overall wear.
