Does this have any practical value? Absolutely not. But does it add some spice to the day? Absolutely yes! Made of Solid Brass and rubber. Simply squeeze to produce a very loud and surprisingly deep-throated honk. It gets attention, we can promise you. Originally produced for cars 110 years ago to navigate the bustle and noise of busy byways clogged with carriages, carts and mules. It is a beautiful piece of hand craftsmanship. We just couldn’t resist it. It makes us smile. Honk!
