For everyone's information the values in the book are based on four things, auction results, shows (actual sales, not sticker price), private sales and guessmatics. All of prices in our book are actual prices unless there is a "?" behind the value. I can give you several example of where items in the book sold for a lot more than the prices we put in the book. The values in the book are also a guide not the gospel like Bill said.
This first book was also what I call a "Dream Book" because most of us will never have the chance to buy these items let alone have the money to purchase them, but if you have the chance to buy one below it's value, wouldn't it be nice to have an ideal of value?
We are just starting to work on our next book. It will have more oil companies plus service station accessories, like tires, batteries and the such.
If anyone has an question or wants to discuss anything in the book or anything you can call me at 217-259-7059.
Also I am looking for photos of rare & unusual tire & battery signs for the next book.
Thanks Dan
