Dating to 1953, "Plywood the Miracle in Wood" was sponsored by the Douglas Fir Plywood Association (later known as the American Plywood Association). The film shows logging operations in the Douglas fir lumber regions, the manufacture of plywood, and its major uses for industry and home. Apparently an updated version was released in the 1960s.

Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
