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
Peter Schlumbohm’s U.S. Patent 2,241,368, granted May 6, 1941, describes a filtering vessel built around a conical paper filter and a narrow central passage. The design joins laboratory clarity with the proportions of a useful household object.
Three large figures move from section to profile and plan, making the glass form and filter path immediately legible. The restored sheet keeps that spare modern geometry intact in black archival linework on a cool old-page ground with a simple black border.
Printed to order on 325gsm museum-grade archival matte paper with fade-resistant archival pigment inks. Made for kitchens, coffee bars, design studios, and collections of twentieth-century utility.
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.
