From the Nov, 1938 issue to Mechanix Illustrated, a sweet little pop-up camping "house" that folded down flat and could be strapped to the roof of your hupmobile, tin lizzie any other jalopy you find yourself piloting.
FEATURING six windows fitted with slid-glass and permanent screens, a newly developed prefabricated collapsible house which can be carried on the roof of an ordinary passenger auto enables sportsmen, fishermen and others who like the outdoors to enjoy short or prolonged trips in perfect comfort. In its compact form the folding house measures only 6x9x2 feet. For protection to the car and to facilitate loading and unloading, a metal frame is used to support the house during transit. The frame can be clamped to the car without drilling and is easily removed. The photos above show the house being transported, unloaded, set-up and used by four persons.Collapsible “Home” Carried On Roof Of Automobile (Nov, 1938)
