Triplicate Deck, 1883, New York, Andrew Dougherty, 52 of 52 cards. Double-ended courts, indices, round corners. On October 11, 1875, Andrew Dougherty of Brooklyn, NY received U. S. Patent No. 168,626 covering placement of a miniature card at the upper left and lower right of each card that partially covering the existing suit mark. The following year, Dougherty produced his "Triplicates" deck with a miniature card in the two opposite corners. On September 12, 1876 Robert Chanony of Montpellier (Herault), France received U. S. Patent No. 182,166 which entirely replaced the suit mark at the upper left and lower right of each court card with a miniature card, and also added the suit mark to the right of the court card. On May 29, 1883, Dougherty secured U. S. Patent No. 278,41 which contained three variations to his 1875 patent. Dougherty placed in the margin and to the left of each miniature card, a single colored letter or number which indicated the value of the card and simultaneously served the same purpose as a "squeezers" deck. Dougherty also removed the underlying suit marks from the court cards and placed the suit mark to the right of the court card, as described in Chanony patent. Additionally, Dougherty placed on the left border of each miniature card, and to the right of the "A"on the ace of spades, a vertical line which indicated the suit. A continuous line indicated diamonds, a line broken at one place indicated hearts, a line broken at two places indicated spades, and three line breaks indicated clubs. These line breaks are used in Spanish playing cards. Thus, Spanish card players unfamiliar with French suit signs would easily recognize the suit. Cards in generally fine condition, With leather case, not original. Dawson, 71, AD13.
