Designed in 1959 by the legendary Enzo Mari for Danese Milano, the Calendario Biliancia (Perpetual Calendar) is truly, no pun intended– timeless design. The calendar uses three different strips of fine wood (walnut, beech, maple) for an old-school-style slide/ruler like calendar. Enzo Mari is now actually teaching at Isia in Florence and at the European Design Institute in Milan– what a professor he must be. You can pop by Nova 68 to purchase ($120) or see more detailed photos.
