These 10 Phillips 66 gas station road maps date to between 1960 and 1966. They are all used and have some condition issues. These include some tears, splits, foxing, and staining. The Missouri map has the most damage. It has large tears/splits at the fold lines and significant foxing/staining. The California map also tears/splits at the fold lines. The maps are fragile and have to be opened carefully but all do open fully. These maps are fun to look at. They are an interesting piece of automotive history.
