The Story Behind the Print
Otto F. Rohwedder’s U.S. Patent 1,790,022, granted January 27, 1931, records Otto F. Rohwedder’s bread-handling machine, which centers, feeds, slices, and retains a loaf through a coordinated mechanical cycle.
The large slicing machine fills the sheet with blade frames, belts, gears, supports, and synchronized feeding parts. This restored edition preserves the original Patent Office arrangement in crisp black linework on cool, timeworn rag paper within the collection’s restrained black double rule.
Printed to order on 325gsm museum-grade archival matte paper with fade-resistant archival pigment inks. A natural piece for offices, libraries, workshops, and collections of invention and industrial design.
Colors may vary slightly between screens and the finished piece—the print will always be richer.
