Twin Ignition

Chipping paint.

Where in the world did you find this?

I think the building is an old repair garage. Livingston County in Illinois. I think it still works. Looks like 80 degrees F.

It sure seems to. It's amazing how some things manage to persist. I once found a wall painted with an advertisement for Skelly Tires, and, judging by the car pictured, it had to be from the 1930s, like this thermometer.
