But is it art?

We had a nice visit to Tate Britain today to see the Paula Rego exhibition, out interest heightened after seeing a very good BBC documentary of her life recently, directed by her son.  She's had a fascinating life, from growing up under a dictatorship to eventually living and painting in London.  She's still going, age 86.   This is one of the staircases at the museum which rather caught our eye.  It's not art though!    A long but nice walk home.
