We restore and reproduce forgotten masterworks of graphic design on museum-grade paper — so they can live on your walls instead of in an archive.
The Story Behind the Print
William B. Gruber’s U.S. Patent 2189285, granted February 6, 1940, documents a handheld stereoscopic viewer using a circular image reel, paired lenses, and an indexing mechanism to present successive three-dimensional scenes.
The rounded viewer body, reel, optical sections, and lever details produce a playful yet precise mid-century design study. This restored edition preserves the original patent 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 media rooms, playrooms, studios, and collections of photography and optical design.
Colors may vary slightly between screens and the finished piece—the print will always be richer.
About the Frame
Framed pieces are built to order in solid wood with a 1.125 inch face, glazed in crystal-clear acrylic, and finished with a kraft paper dust cover and hanging wire. Your print is dry mounted so it stays perfectly flat for decades. Each framed piece arrives ready to hang.
The frame adds roughly 1.75 inches to each side of the print size you select. Framed orders are custom made and ship within 7 to 10 business days, free in the U.S. See our shipping and return policies for framed piece details.
