This is a smaller two-sided display from the 1960s. It stands about 2 feet tall by 4 feet long. The "Semi-Mounted Plywood Box" shelter on Panel 4 is actually supposed to be written "Semi-mounded Plywood Box." Several of these designs are shown in model form on this page of this site - Fallout Shelter Model Set. There are models of the Plywood Box Shelter, Concrete Block Shelter and the Protected Above Ground School designs shown on this stand-up display.
