Welcome to the Guild MamaC!
Just found this site after obtaining several vintage maps and trying to find out how old they are and possibly sell them. I love maps. I'm not very good at using them when driving, but how they're made, what they tell, how they look--all that intrigues me.
Well cool. I'll bet if you posted pictures of the maps with as much info as you have we could help out with the process of placing some value to them.
And I don't think anyone is good at using maps while driving... or at least they shouldn't be. Dangerous business that.
