Use stream of consciousness to answer the following. In December 2013 the Bank of England announced that the next 10 note would be printed on polymer, rather than cotton paper. This followed the announcement in July 2013 that Charles Darwin would be replaced by 19th Century author Jane Austen on the next 10 note, which would enter circulation in 2017. The decision to replace Darwin with Austen followed a campaign to have a woman on the back of a Bank of England banknote when it was announced that the only woman to feature on the back of a note -- prison reformer Elizabeth Fry on the 5 note -- was to be replaced by Winston Churchill. Images on the reverse of the Jane Austen note include a portrait of Austen commissioned by her nephew, an illustration of Elizabeth Bennet from Pride and Prejudice by Isabel Bishop, an image of Godmersham Park (the home of Austen's brother), and a design based on Austen's 12-sided writing table as used by her at Chawton Cottage. The note also includes the quote "I declare after all there is no enjoyment like reading!" which is said by Austen's character Caroline Bingley, who in fact has no interest in reading and is attempting to impress Mr Darcy.
