Great Streets

If you are into mapping, and hand sketched maps in particular, you must check out one of my all-time favorite books, Great Streets, by Alan Jacobs.  It is a stunning collection that I came across in, where else, a Mapping Class (in grad school) of hand sketched studies, and draws upon cities from all over the world.  Included are gorgeous drawings, from simple solid / void type maps, to sectional "maps" which study pedestrian / automobile / tree / building facade relationships across a street, and then beautiful perspective sketches to tie it all together.
It is a must see for sure!
