What is it about a flip calendar that is so irresistible? Why do we instinctively just need to keep pushing the cartridge over and over and over, to see the numbers keep changing....the need to twirl the knobs that change the name of the months and days of the weeks? Is it the utter simplicity of the design that we find so fascinating or is it is the concept of time itself? Who knows....in any event, a flip calendar on a desk is a joy. This one is small and works well. The calendar is in good, age-related condition -- the silver metal has acquired a nice aged textured patina.
