Question of the week: what’s your favourite work of art?

It says somewhere here that this is a blog about the media in general, rather than just TV or film. So for a little change of pace and to fulfil the blog’s mandate, it’s time for a simple question:

What’s your favourite work of art?

It can be a painting, a sculpture, an installation, a piece of architecture or anything else arty.

Answers below or on your own blog, please!
