What is the most comprehensive database of companies that sold gas throughout US history? I am going to eventually create a fictional name for my backyard biofuel "station" and want to choose something so as not to confuse the hard-core collectors. Instead of remaking or buying reproductions of real signs, globes or other items, I want to create a logo that would have been correct if such a name existed in the mid 20'th century. Just don't want to use a name that existed and confuse some collector 100 years from now who may be deceived into thinking the stuff is valuable.
