This map is the third edition of Jacob De Cordovas 1849 map of Texas, which was one of the most important post-annexation maps of the state. This version features Texas in its present configuration, shortly after the Compromise of 1850. The inset shows Texas in context with parts of the American Southwest and Mexico, and includes the Panhandle as we recognize it today for the first time in this series.

On the left side of the map, the signatures of several important early Texans, including Thomas Rusk, Sam Houston, and Land Commissioners Thomas William Ward and George W. Smyth attest to the accuracy and quality of the map, which was compiled by draftsman Robert Creuzbaur from Land Office records.
