Airguide Digiguide Wall Thermometer from Airguide Instrument Co., 1960s, Works

Retro wall thermometer in “atomic” elongated oval shape from Airguide Instrument Co., Chicago, USA. Liquid Crystal Display is slightly difficult to read but it does work. Measures temperature from 66 degrees up to 86 degrees. Display readout is surrounded by a gold insert, which reads Airguide. The entire unit is plastic. There is a hole in the upper back for hanging. It measures 12.5” x 2.75”. I think this was manufactured sometime after the late 1960s, when liquid crystal display was invented. AGTHERM100
