Our own Nick Rallo, who knows of my fondness for old maps of Dallas, directs my attention this morning to today's posting on the Big Map Blog: Sam Street's Map of Dallas County, which dates back to 1900. It's especially interesting in that it details who owned what and where all the way up to Carrollton, including some quite-familiar names for whom streets and schools would one day be named. And today's post, culled from the archives of the Texas Historical Commission, also points us toward another one on the Big Map Blog last month: A Literary Map of Dallas, created by the Dallas Public Library in '55. Hmmm, needs an update.
