Some streetart from an unkown artist, he/she creates many pieces in the Amsterdam area, but when looking for it there are multiple pieces in Amersfoort as well. The art is not easy to reach or accessable, as it’s near the railroad. When driving bij car over the Zielhorsterweg you can spot them easily.

 Seems this artist has it’s own IG account Sick Society : https://www.instagram.com/__sicksociety__/?utm_medium=copy_link&fbclid=IwAR0pL8k7bRNwQSdhrr9tJj0ugMdlNEk4rq1xFeEHBJnU9Ny6f3iLtuoVom8
