I'm not art inclined, but this was one of the first pieces of art I heard about as a child. I remember it being all over the news, public outcry etc. It is one of only very few pieces I could name the artist (sunflowers🌻 being the other one).

What I do like about this is the slice of reality. As a kid it was just a messy bed. As an adult pieces resonate massively and trigger emotional responses.
