This is where all of us started, back in the early 1980s I brought every sign (even cigarette signs) home, I just loved old advertising, but leaned heavly toward petro items.
Read all the posts here on Old Gas, go back and read some of the old ones, get yourself knowledgeable about what you are looking for. Buy the books that tell you more about the things that interest you. You can't ever have too much knowledge.
