This is a rare set of pilot goggles, by American Optical Company, in the original case. The top of the case reads “AVIATION GOGGLES AMERICAN OPTICAL COMPANY” with the company's winged logo and five stars. The bendable bridge of the goggles is in the shape of two interlocking wings. The frame holding the lenses have slanted slots along the top and holes along the bottom to eliminate condensation. On the frame is written "American Optical Company" and "Made In The U.S.A." The rubber and leather that the seal is made of is dry and cracked, but for an item of this age that is not unusual. The case is in good condition for its age. The case measures 8" X 4" X 3".
