Personally I don’t have a wall calendar, but I know people who like them, and here is something for them. The Perpetual Wall Calendar – No.1 is a simple vintage 1970’s German-designed plastic perpetual wall calendar that looks awesome. Numbers and days of the week can be manually rotated to designate the proper day and date.  The calendar measures 10.25″ in diameter and is in good overall vintage condition, but does show surface wear. This wall calendar is sold here.- Via – Swiss Miss
