Adorable perpetual brass calendar. Mounted on a slab of marble with a brass mouse and trap. Trap is spring loaded and does move up and down to place papers under to keep them secure like a paper weight of sorts. Mouse has the cutest little face and pink ears. Calendar has black numbers on pieces of square metal from 1 to 31 and is in working condition. Marble base measures 3 1/4" x almost 2" wide. Has original foil seal on the bottom "A Parkdale Novelty Toronto". In great working condition. Check out the photos.
