The automobile was very well established in San Antonio by 1910. With a population of 96,614, SA was the largest city in Texas. The first gasoline powered horseless carriage, a Haynes-Apperson, had arrived just nine years earlier in 1901. According to the directory, created by the "Western Auto Directory Company" based on Kansas City, there were over 750 vehicles - electrics, steam, and gasoline powered - registered in Bexar County. There were also multiple dealerships for all kinds of new and used cars. Finally, the directory shows a large number of businesses existed to provide every kind of vehicle service imaginable from basic maintenance, painting, parts replacement and insurance. Not one of the businesses listed remains in the present day.

The directory was very much 'pay for play.' While there are nine places listed to get your electric vehicle recharged, there is only one place listed that sold gasoline. Filling stations as we would understand them are not mentioned. The first in the US were opened around 1907 in Missouri, Streetside pumps at existing businesses with gas tanks in upper floors to provide gravity flow delivery almost certainly existed but concrete eveidence has yet to be found. The first purpose built "station" in San Antonio, with pumps on a raised island under shade, opened in 1917.

Many notable names appear in the list of early vehicle owners. George Brackenridge had two. The Frost banking family had several. Guenther, Herff, Nix, Joske, Steves, and Topperwein are all mentioned. However, Brian Callaghan, the mayor of San Antonio in 1910, is not to be found. Nor is noted early San Antonio motoring pioneer and enthusiast Dr. R.A. Goeth. He is probably among the first of the missing nine owners (see page 11 or under Local Information). He was one of the thirteen charter members of the San Antonio in 1904. The first independent Ford dealer, Clifton George is listed, but not what kind of car he owned. Businesses such as dairies and real estate companies are also listed

Ford and Oldsmobile, the two most popular car manufacturers at the time, are conspicuously absent from this booklet. The Ford Motor Company opened a factory outlet immediately behind the Alamo in 1908. It has yet to be determined exactly when Clifton George took it over as an independent dealer. For their own reasons, the folks selling them decided not to pay for space in this publication. REO, formed by Ransom Eli Olds after he left Oldsmobile in 1905, is also not listed. Oakland, which would be renamed Pontiac gets one brief mention.

Despite having automobiles for less than ten years, San Antonio already had a significant infrastructure system to support the ever growing number of vehicles in Bexar County by 1910. As well as regular repairs, the directory shows companies providing accessories, batteries, driving lessons, insurance, oil, painting, parts, repairs, repair equipment, rentals (then known as livery service), taxis, tires sales, tire repairs, upholstery, and even ambulance service.

Not all service providers paid for a full sized advert, but are instead listed on the first two pages of the booklet provided below.

While nine different places to get an electric vehicle charged are listed, there is only one place that mentions refilling gas tanks. ,
