I wonder what colour this van was originally? - silver/aluminium?
"...And so the Parade got is appropriation. The caravan itself – vehicles, personnel, exhibits, props, tents, etc. – took most of 1934 and 1935 to prepare and assemble. Focal point of the Parade was the fleet of eight huge, red-and-white, streamlined vans. These were custom built in Fisher body’s Fleetwood plant in Detroit. All eight spanned the 223-inch truck chassis and were powered by GMC gasoline engines. Six of the streamliners formed walk-through exhibits when joined together, three by three, with canvas awnings. Another van opened up to form a stage, and the eighth carried equipment."
