I recently picked up two signs. One is a DSP 42'' Simpson Oils sign. Nothing else like it. Another is a Shell Motor Oils sign with austrian/german text on bottom right, also very heavy for its size. 1) Anybody ever heard of Simpson Oils?? 2) Any idea of value on this one of a kind sign and/or the Shell austrian sign? Shell is roughly 20'' x 24''. Thanks for the help!
