A while back I found Motoring Tourists and the Scenic West, a 1989 catalog authored by Michael Vinson for the DeGoyler** Library at Southern Methodist University in Texas. Although the Coastside is NOT mentioned, I found it entertaining, with color and b/w photos of vintage travel posters.
Also, De Goyler Library specializes in the history of some American railroads—and they may hold Ocean Shore railroad pix in their archives.
Here’s the catchy chapter headings:
1. Select Your Motor Car!
Automobile Sales Catalogues
II. It Won’t Start!
Automobile Instruction and Mainentence
III. How Do We Get There?
Highway Guides and Motor Camping
IV. Let Someone Else Drive!
Organized Touring and Travel Promotion
V. We Motored West!
Narrative Accounts of Early Automobile Travel
**Everette DeGoyler, a famous petroleum geologist, became a legendary figure in the Texas oil business.
