For your consideration a rare vintage c.1920s McKesson\'s Drug thermometer advertising Aspirin. The thermometer is made of metal and has a porcelain finish. The glass tube is good and works. There is some damage to the finish at the top and bottom where it was hung. It measures 7\" in width by 27\" in height. An excellent addition to any advertising collection or if you just want to own a really neat old thermometer. Made by Beach.
