3.5" dia. by .75" deep metal frame with tin litho thermometer insert. Mid-1930s by Character Art Manufacturing Co. Back is designed with both easel and loop for hanging. Depicts Mickey standing atop Pluto's dog house holding a stick over top of him. Designed with separate tin piece for Mickey's head and arm holding stick and the stick itself is designed to point at the temperature. The few examples of this we've offered in the past had a square case, this is the first we've seen of this round case variety. Typical scattered wear/aging with some scratches to the metal case. Few pinpoint paint nicks on the insert. Fine.
