What makes this calendar especially unique is that each page is done in a different typeface, and includes a brief biography of the typeface creator. Perfect for the office or the home of anyone that appreciates clean, modern design.
(We love it so much, it's also conveniently available at our AT store!)
Another similar calendar that we also love is the classic wall calendar by Stendig. Based on the design by Massimo Vignelli in 1966, the original is on permanent display at MOMA. You can get the 2007 version at Crate&Barrel.
