Via @neomischa on Twitter, here’s a beautiful old map of the Twin Cities, published especially for the Dual City Blue Book in 1901.
The “Dual City Blue Book” was a kind of map and guide, sort of a combination of Yellow Pages, street atlas, and Happenings’ book of its era. It describes itself as a “private address directory, ladies calling and shopping guide, for St. Paul and Minneapolis [with] names of eighteen thousand householders, arranged alphabetically and classified by streets.”
I totally want one of these! You can page through them online at the Digitial Public Library of America archive.
