The U.S. Postal Service is honoring pioneers of American industrial design with twelve new Forever stamps. Earlier this week at a ceremony at the Smithsonian’s Cooper-Hewitt, National Design Museum, the all-new Pioneers of American Industrial Design stamps were unveiled. The stamps focus on innovators of Machine Age products that emerged during the Depression. Many of the of the designers featured were inspired by the Art Deco style of the period, and many products were streamlined and reminiscent of planes, trains, and transportation design. A sheet of 12 stamps can be purchased for $5.28 at post offices, or online at the USPS online store.
