[Slots Machines] Directions for Operating Mills Operator’s Bell Counter O.K. Mint Vendor. Front O.K. Mint Vendor. [cover title]

[Chicago. 1929]. [16] pages. Illustrated self-wrappers. Well-illustrated. Some old ink numbers to both covers which have mild wear. Clean and sound within; Very Good. Rare and original slot machine publication from the auspicious year of 1929. This detailed and abundantly-illustrated manual provided Mills slot machine and arcade game owners with all of the information they needed to keep their Mills "Operator Bell" machine running efficiently for uninterrupted profit-making. Often-cheaply-made facsimiles of operator’s manuals for early American arcade games are now plentiful. The original manuals are rarely found, likely given their small printing runs and their ephemeral nature. zxc.
