Online retailer Ken Knight sells two of our favorite calendars: Pentagram's typographic version, which features a different typeface each month, and Massimo Vignelli's classic Stendig, a bold black-and-white calendar in Helvetica font.

The online store also carries portfolio book sets and presentation boxes in the same streamlined style. Targeted towards designers, the inventory is straightforward and simple. Ken Knight is based in Tennessee and ships anywhere in the United States. For more information, click here.
