The Helmar H813-4 Boston Garter series consists of 45 cards, and the design was inspired by one of the most beautiful baseball card sets of all time, the 1912 Boston Garters. The originals showed the sock garters; the Helmar versions instead show interesting scenes in the background or period detail such as a 1912-era telephone. Each card is large at 8.5" x 4.25" and gorgeous. Produced in 2014. In the fall of 2021 the series was extended with a round, 2.5" dexterity hand puzzle made to match each earlier card in the series. Each hand puzzle consitutes a game piece that includes three dice with outcomes detailed on the puzzle's backs. Two new players were introduced within the series extension, #47 (Lazzeri) and #81 (Cravath). Additionally, the last two puzzles feature John McGraw in multi-player illustrations. The back of #83 features a checklist.
