Back in the 1960s there were seven of these mobile cinemas made for the Ministry of Technology. There is now only one left. Come on board and hear its history. Meet the owner and watch a short 10-minute film. Showing all day (every 15 minutes approx) until 6pm. Free entry. Nicknamed Audrey, learn about her celebrity status including TV appearances on George Clarke's Amazing Spaces and Melvyn Bragg's Reel History of Britain. This is one short show that will be one of the highlights of your trip to this year's Edinburgh Festival.
