Robert Smithson but also,, Anish Kapoor

Reading about Donald Judd getting upset having his art reproduced not because of it's original site specificity but because HE was not the one reproducing it made me think a lot of Anish Kapoor and the fact that he patented the shade Vantablack so no one else could legally use it:

Also, I researched a more in depth analysis on Smithson's theory of non-sites because I was really confused:

I had heard of Smithson before but wanted to refresh myself with some of his works. I got all of these images on good ole google!
