$20. signs-

[quote=okoil1]I will be in the minority but all 6", 8" and 10" heavy porcelain sunray signs might be fantasy.

Several were made circa 1979 and again in 1989 at Sourhwestern Porcelain in Sand Springs OK. Earlier versions have a dark gray back and later ines a lighter/medium gray back. All have split grommets and excellent shelving.

I've never found any compelling evidence that these were used on pipelines or even pumps.

The new description takes on a bit of the old Iowa Gas auction as both signs now are described as "Porcelain Contemporary"
