Honoring 12 of America’s most influential industrial designers, the Pioneers of American Industrial Design Forever Stamps ($5) were reason enough for us to make a beeline to the nearest post office today to pick up a few sheets (one to tuck away for an heirloom, of course). Released on June 29, each Forever Stamp highlights pioneers like Robert Heller, Peter Muller-Munk, Donald Deskey, Walter Dorwin Teague, and Henry Dreyfuss and their iconic, aesthetic-setting creations. What better way to commemorate 20th century design.
