Rare French Art Deco 1930s Bakelite perpetual calendar. An unusual desk accessory in a lighthouse-shaped design with red tea amber marble and apple juice Bakelite. The lighthouse turns on its base manually to adjust the day (initials in French) to the date (on the base). The numbers on the base are visible thru geometric carved windows and are engraved on white Galalith plaques. In excellent working condition. No visible maker's mark.
