Hey to all. In my random meanderings around the interwebs I seemed to have stumbled across an interesting source of out of copyright maps. Check out Vintage Printables. I will admit that it is not the most organized site, but I found some excellent Paris city planning and layout maps there are great sources of inspiration. Apparently the owners of the site are having some server issues, so the easiest way to look through all of their uploads is to go to the "Browse All Images" tab and run your own searches.
