Basquiat- definitely one of those paintings that look better in real life than a photo- it’s huge when you see it in person, about 4m long and there’s different layers of colour
Malevich’s black square on the cover there is pretty eerie when you see it in real life. I went to the exhibition at the Tate a little while ago, and they had it hung in it’s original presentation. Public buildings in Russia in those days used to have a religious icon hung in a corner by the ceiling, and he hung a big black square up there instead at his show as a kick in the face at the church, which is why people made such a fuss about it at the time.
