California (ACSC) Warning, 29 Miles Mountain Road sign

Description

In the early 1900s, before the state got involved with highway signage, the Automobile Club of Southern California (ACSC) installed directional and warning signs across Southern California to help drivers navigate challenging terrain. These signs have become rare and highly sought-after by collectors. One memorable sign appeared at the start of a rugged 29-mile mountain stretch, urging drivers to keep right at all times and reduce speed to 15 mph around sharp curves. Like the majority of ACSC issue of the time, the sign was diamond-shaped, with blue block lettering, a white background, and the words “AUTO. CLUB SO. CAL.” surrounding the club’s iconic bell logo.

Bring the spirit of early Southern California motoring history right into your home, garage, or business with our Warning, 29 Miles Mountain Road Sign. This iconic replica captures the bold look and practical design of the original porcelain-enamel road signs that once warned America’s very first motorists of the new hazards awaiting them on the open road. Authentic originals can cost hundreds—or even thousands—when they appear for sale. But you don’t need to wait for a collector’s auction to add this historic treasure to your decor.
