If infinite regression is your bag then Jason Polan has a book for you.
Artist, Polan has drawn every single work of art in the New York's Museum of Modern art and published the results as a book.
The Every Piece Of Art in The Museum Of Modern Art Book contains every piece of art that was visible to the public at the museum from January 19 to January 31, 2005. It is 50 pages and perfect bound.
Insert pun about art imitating art. Sorry.
