I wouldn't put most of the legendary pieces on my wall unless you paid me.
edit: it always tickles me the negative reactions I get when people hear my opinion on art. Doesn't seem to matter how I phrase it, it's always offensive to someone that I can't see the undeniable beauty in popular art. Putting time and effort into something is a prerequisite for me to be in awe, but it does not automatically interest me. Many professional athletes put in far more time and effort into their craft to play a decorative game and I similarly don't care about their mastery of their strictly decorative achievements.
