Sorry for the poor photo quality, but my camera SUCKS..... (I'll delete that if I need to)
If your talking about this Pyramid Oil Company, they do nothing other than drill for and pump oil, then sell it to whoever buys it. They have never had a "Retail" marketing operation.
There was a Pyramid company in New Jersey though.

Lets see a pic of the sign. If you cant post it, e-mail it to me and I'll post it for you.....
