Harmonious, Vibrant and Clear - Cicca Car Horns

Ads don't come any better than this really... 1926 ad for Cicca car horns.

A Cicca horn will precede your car and avoids wasting your time by accidents; so frequent when driving and at dangerous crossings. 
With the increasing intensity of traffic, and the crowd of novice drivers, it is unwise to make the journey without a serious and powerful horn. 
Your safety requires an electric "tenor" Cicca (easily installed at your local garage).
