A very cool mid-century modern (possibly Scandinavian) white plastic perpetual calendar. Allows for setting the month and the first day of each each month so the dates line up with the correct day of the week, as well as including red framed pieces to highlight dates and white pieces to cover up any additional days of the month (e.g. 29, 30, and 31 for February.)
In good vintage condition with wear consistent with age and use.
