Addressotype Slab is based on lettering from a vintage ad for the Addressograph-Multigraph Corporation, manufacturers of the Addressograph addressing machine. In days when the U.S. postal service delivered everything, mailing addresses were as important as email addresses are today. The Addressograph machines stamped out dog-tag-like plates that were used to print mailing labels at high volume. Embodying the company's work ethic and durability, Addressotype recalls the gaspipe form of lettering popular in the 30s and 40s, updated to reflect the "streamlining" trend popular during the period.
