-Does an artwork (/sculpture) necessarily need to be made of metal or of solid materials? This is made of paper.
-Does it need to be giant in size (to get to be ‘noticed’)?
-Does it need to be in the gallery?
-Isn’t the shadow part of the work (and it would change depending on the circumstances of light)?
-I didn’t bother to preserve the work. Can you guess why?
-The same work could have been created by Richard Serra or it just reminded me of him.
-The tape or doodle on the work says a lot about the non-seriousness of our time.
