Unusual Perpetual Easel Desk Calendar - retailer Bakelite/Celluloid Retro Office Accessory

A most unusual desk accessory, this round perpetual calendar has a graphic of a seated man playing a horn for a goose, while having movable slots for the day of the week, the month and the date. The entire contraption has an easel back and works beautifully -- each knob does what its supposed to. the front of the calendar is made of a pearlized material that reminds us of celluloid. The piee is in good, age-related condition -- there are no cracks or chips.
The calendar is approx. 5 3/4" in diameter. retailer
