This is a lot of vintage works from start to finish on a brochure project for Sperry Avionics Corporation. The brochure which includes aircraft information, and safety was made for passengers flying on a Sikorsky S-76. 3 folders total which 2 that include sketches on wax paper and notes measures each about 20 inches by 15 1/4 inches. And the other includes artwork for the front cover of the brochure which measures just under 15 inches by 13 1/2”. The Helicopter itself in photo measures about 9 inches across. One of the brochures is the layout rough draft which the glued front cover came off of. This lot also includes the final product which is seen in photos. A very unique oddity lot for anyone who may collect aviation or other similar items. Message with any questions. Everything is as seen in photos. A few small stains or spotting mostly on cover of folder. This is from the estate of a previous employee who worked for Sperry and is a one of a kind lot, Not a reproduction or copy.
