Designed by Rob Cerneus, this striking bronze statue of a man wearing a simple suit and a cap may not ring any bells at first, but the noisemaker in his hand holds the key to his story. For decades, men like these would walk around Amsterdam’s neighbourhoods causing quite a racket, but they were actually paid to do this. In fact, they were sanitation workers who let local residents know that they could bring their rubbish out onto the street to be collected. In 2007, this statue was erected to honour 130 years of sanitation services in the city.
