Created in 2019, this artwork is the result of a collaboration between two artists: Tanja Prill, from Hamm, and Wojciech Brewka, from Kalisz. Their collaboration is no coincidence, as Hamm and Kalisz are twin towns, and the mural symbolises their friendship. The project was coordinated by the Bogdan Jarecki Visual Arts Centre “Wieża Ciśnień” in Kalisz. Wojciech Brewka drew inspiration from the Muzykanci sculpture located in the city park.
