One of the earliest obtainable maps of Las Vegas, Nevada,
Incorporated in 1911, Las Vegas is the fastest growing American city founded in the 20th Century. The present map show the new Airport and lands owned by Boulder Airways, suggesting the map was printed sometime between 1920 (when Randall Henderson landed the first airplane in Las Vegas) and 1926, when Western Air Express conducted the first commercial air service. We were not able to locate any sign of a Golf Course in Las Vegas (first golf course built in 1927).
Thomas Bros. Maps was founded in 1915 in Oakland, California, by cartographer George Coupland Thomas and his two brothers, who developed a distinctive page-by-page grid system of mapping cities that eliminated the need for clumsy folding maps. The maps were bound in a convenient book format that became known as the "Thomas Guide." Since then, Thomas Guides have become the standard street reference for drivers in many West Coast communities as well as for police and fire departments, utilities, realtors, and local governments.
