Jenny Beorkrem is a 24-year old Chicago designer who launched typographic neighborhood "maps," Ork Posters, in November of last year, and quickly sold out. Here's a look at her San Francisco map:

Jenny's Boston, New York City, Chicago, and San Francisco maps cost $27 each as screen prints, a little less as posters.
