Downside up

Have you ever stood on your head and looked at artworks upside down? Probably not. So to save you trying that have a look at this exhibition, which allows you to recognise that often images are just as interesting upside down. If you think this is nonsense, then you missed the October 2022 announcement that a great masterpiece by the abstract Dutch artist Piet Mondrian has been hanging upside down for 75 years and no one noticed.
