Hello everyone,
i have a porcelain sign that I am trying to identify. It has kind of a cream-colored background and across the bottom it says:
"STOPS CARBON KNOCKS". Above that is a square area of which the four corners are colored black. In the center of that area is a red diamond with "NEVR NOX" in black and below it a horizontal red arrow with points on each end which says "GASOLENE" in the creambackground color. Below that, in smaller, black letters is: "NON-POISONOUS".
Can anyone tell me about what company this was from or anything else about it?
