First National Bank Prague Okla Advertising Thermometer

Advertising thermometers like these are something I run into fairly often. In fact I have one from a poultry hatchery. These all have the same metal body and white with red trim.
This one is for the First National Bank in Prague, Okla (now known as OK). Hard to tell if the bank is still around. Seems to be a credit union now.
Anyway I recall the First national Bank was always getting robbed in old movies. Calling all cars calling all cars the First National bank has just been robbed. Be on the lookout etc.
The thermometer 12 1/2" x 3 3/4".
