Large 23x18" color poster showing artist concepts of heavy lift helicopters for both the US Navy and Marine Corp. This is a typical item produced in small numbers at a time the company was trying to sell the military on a new concept. Not surprising that it resembles the Sikorsky Sky Crane. Text at the bottom of the poster reads: "Hughes Reaction Drive/Heavy Lift Helicopter System; Hughes Tool Company/Aircraft Division; Culver City, California". Excellent in a frame of slightly larger size. Will ship rolled in a tube or for extra postage in the frame.
