I recently came into hundreds of vintage road maps. They are State issued, AAA issued, and oil company issued (including Esso, Texaco, Standard, Hi-Speed, Chevron, etc).
Overall they are in great condition. The majority of the State issued maps are from the '60's & 70's, and from what I have seen the oil company maps are '50's and 60's.
I have no idea what their value is but I know they are worth something to someone.
Let me know what you are looking for and I will see if I have it - there are literally hundreds of them (too many to list).
I will try to upload some pictures.
How about $2/each, or make me an offer on the lot.
