Official Automobile Blue Book, Vol. 7

This practical motor guide served drivers navigating America's early automotive age. The blue cloth binding and gilt lettering signal a reference work designed for the touring motorist—essential for route planning and mechanical troubleshooting before standardized roads and modern infrastructure. Published during the post-WWI automobile boom, when car ownership surged and cross-country travel became feasible for middle-class families, the Blue Book functioned as both directory and manual. Its comprehensive listings of garages, repair shops, and road conditions made it indispensable for motorists venturing beyond their home regions. Such guides documented the rapid transformation of American transportation and leisure in the 1920s, a decade that redefined mobility and independence through the automobile.
