Vintage desktop ADVERTISING thermometer. Right from an estate sale. I am guessing this is from the 70's or so.
"NAU GRAIN CO" Plain City, Urbana, and West Liberty, OHIO.
4" wide and 2 3/4" tall.
Appears to work. No cracks or chips. Could use a little cleaning to be perfect.
It will be protected well and insured.
