My mother has a pen with this feature (printed eternal calendar inside a rotatable sleeve) in the 1960s. It lasted many years. Good to know someone has finally invented it.
- acomjean 4y agoI was wondering what that would look like. https://www.worthpoint.com/worthopedia/vintage-parker-cathay-pacific-ball-3826678541 https://www.worthpoint.com/worthopedia/vintage-parker-cathay... We had a giant plastic wall hanging perpetual calendar in the 1980s. "Ring-A-Date Perpetual Calendar" I guess as a kid I got used to the grid of days not always starting in the same place. https://jukiamsterdam.com/products/ring-a-date-perpetual-calendar-by-giorgio-della-beffa-green https://jukiamsterdam.com/products/ring-a-date-perpetual-cal...
- bregma 4y agoYep, that was the pen (minus the corporate logo). I guarantee it was endless minutes of fascination to a child fascinated by things that do thought work. Don't get me started on her slide rule.
