The cards in this 132-card set measure approximately 2 1/4" by 5 1/4". The 1912 T202 Hassan Triple Folder issue is perhaps the most ingenious baseball card ever issued. The two end cards of each panel are full color, T205-like individual cards whereas the black and white center panel pictures an action photo or portrait. The end cards can be folded across the center panel and stored in this manner. Seventy-six different center panels are known to exist; however, many of the center panels contain more than one combination of end cards. The center panel titles are listed below in alphabetical order while the different combinations of end cards are listed below each center panel as they appear left to right on the front of the card. A total of 132 different card fronts exist. The set price below includes all panel and player combinations listed in the checklist. Back color variations (red or black) also exist. The Birmingham's Home Run card is difficult to obtain as are other cards whose center panel exists with but one combination of end cards. The Devlin with Mathewson end panels on numbers 29A and 74C picture Devlin as a Giant. Devlin is pictured as a Rustler on 29B and 74D. Listed pricing references cards in raw "EX" condition.
