Interesting large format map of Eastern Texas, hand colored by counties, from Asher & Adams' Atlas of the United States.
Conceived as a railroad atlas, the map gives a very detailed treatment of the rail lines and stations. Large inset of the region between Brownsville and Corpus Christi. Shows towns, railroad lines, stations, etc. Post offices are also located. One of the most interesting large format commercial maps of Texas from the early 1870s.
