For your consideration is an original signed McClelland Barclay vintage early 1930s copper/brass Cupid desk thermometer.
The item measures approximately 4 3/4" wide and approximately 2 1/2" high. The round glass thermometer, including the rim, measures approximately 2 1/8". The thermometer is a made in U.S.A. Pat. No. 1926808, indicating a 1930s patent. It is marked/signed McClelland Barclay on the back bottom right, although difficult to see in the photos. It is very nice vintage condition and a rare collectible item. I cannot guarantee that it is working accurately, but the red thermometer hand does fluctuate with changes in temperature.
Please see the photos as they are part of the description.
