My first thought was this artwork: https://www.artlist.cz/en/works/poznamenana-krajina-6289/ Its author was known for his "structural graphics". "He often used the flaking walls of Prague streets on which he would demonstrate his visions and try to show that it is possible to find pictures in everything around us, without the need for any particular education, simply by using our imagination and through visual associations." (more about his work here: https://www.artlist.cz/en/vladimir-boudnik-101681/ ).
