It's a tough life being a world-famous piece of art. You don't get to move, you have no privacy, and every day thousands of strangers gather round to stare at you and criticise.
A piece of art gets looked at constantly, yet we never consider what it would be like were the roles reversed; that is, until this extremely clever Tumblr was founded.
It's called What They See, and has only been running for a few days, yet has already posted an excellent selection of 'painting-eye-view' photographs, all taken at the Metropolitan Museum of Art in New York.
Take a look at a selection below - some have been luckier than others with their vantage points.
