Edgar Tobin Aerial Surveys of East Texas Collection, 1930s.

Edgar Tobin Aerial Surveys is an aerial survey and mapping company based in San Antonio, Texas. The Edgar Tobin Aerial Survey Collection depicts the East Texas landscape during the 1930s, including the locations of oil and gas wells, cities, towns, railroad lines, canals, rivers, creeks, pipelines, railroad logging spurs, and logging scars. The surveys also show towns and settlements no longer in existence (mostly connected to the lumber industry), railroad lines that have been abandoned, and how East Texas appeared prior to most modern highways and the creation of Lake Sam Rayburn.
