In 1912, the Police Prefecture of Paris organized a mudguard car contest which attracted many inventors involved. The effectiveness of their inventions being measured by rolling their cars on the streets in a rainy day with blank panels.
The attendants at each panel appear to be equipped with a bucket of water and a brush, presumedly for cleaning off the panels after the results for each car were recorded. Four types of anti-splash devices seem to be the most commonly used: metal guards, brushes, chains and round metal, leather and rubber discs mounted to the outside of a tire.
