Julia Child kept this signaling mirror in her kitchen junk drawer as a reminder of her service in the Office of Strategic Services (OSS) during World War II. Such mirrors were issued to members of the military, merchant seamen, and others, like OSS personnel, serving abroad. Julia’s OSS duties took her to India, Ceylon (Sri Lanka), and China in 1944-45.
This mirror is model 40653, manufactured by General Electric. Small and compact, it could be used to signal for assistance over a 10-mile distance. Instructions for using the mirror are provided on the device, which also includes a braided lanyard for wearing around the neck.

Comments

My Father, Wentworth M. Potter, invented this Emergency Signaling Mirror while working as an Illumination Engineer at the Engineering Division, Lamp Department, General Electric Company, Nela Park, Cleveland, Ohio. He wrote a paper on it that was published in Illuminating Engineering, Volume XXXIX, No. 4, April, 1944. The title of the paper is "An Emergency Signaling Mirror Incorporating High Efficiency with Precision Aiming".
