Guys: Can anybody help the newbies out there determine what 12" round PPPs are real and which are fantasy signs? I have been told that Mobil(round), Texaco, Phillips 66(orange & white), Lion, and Shell(yellow claim shell) never made an 11"-12" PPP. Is that correct? What about: Mohawk, Humble, Washington, Musgo, White Rose, Frontier, Buffalo, Sunset, Pure, Magnolia, American, Red Crown, Gilmore, Sinclair HC & Dino, Hancock, Standard w/ flame, etc. These ubiquitous signs are flooding the market. Any answers to these questions will help us determine who's responsible for the proliferation of these signs on sites like EBay and help us to target them and shut them down. Thanks Keith
