"The visual deception arm of the Ghost Army was the 603rd Camouflage Engineers. It was equipped with inflatable tanks,[7] cannons, jeeps, trucks, and airplanes that the men would inflate with air compressors, and then camouflage imperfectly so that enemy aerial reconnaissance could see them. They could create dummy airfields, troop bivouacs"
"Many of the men in this unit were artists, recruited from New York and Philadelphia art schools."
