Sketch On Envelope For Pocket Brush (USA), ca. 1935

This is a Sketch on envelope for pocket brush. It was made by Joseph B. Friedman. It is dated ca. 1935. Its medium is pencil on paper.

Joseph Friedman’s best-known invention is the flexible straw, but the range of his inventive activities encompassed writing implements, improvements to engines, and objects for personal care, including this sketch for a seemingly simple pocket brush. Friedman frequently sketched on loose scraps of paper—he was especially fond of envelopes—working out ideas and solving problems, as here, where he laid out the basic premise of his invention in very simple terms: "Lays flat. Moves to vertical position to use. Case used as a handle. Brush does come out completely."

It is credited Joseph B. Friedman Papers, Archives Center, National Museum of American History, 2001.3031.
