For your consideration, we are offering this very nice original Quaker State Oil advertising thermometer. This appears to be circa 1970s-1980s production.
The dial has bold, vibrant lettering with good color and no losses noted. The thermometer appears to work well.
This measures about 12” in diameter.
The crystal dome is of plastic. This is of the 2-tab style and has the older screwed together band.
The dome has some scuffing and signs of having been displayed, probably in an auto shop or gas station. The metal band also has some bends. Please see photos for more detail on this great piece.
