• The annual summer exhibition showing work by members of the Royal Watercolour Society and the Royal Society of Painter-Printmakers gives visitors the opportunity to take home original paintings and prints at the point of purchase. Visitors to the exhibition can take the paintings home with them straight away, so the exhibition is constantly changing as sold work is replaced with new. Off the Wall is at the Bankside Gallery, 48 Hopton Street, London SE1, August 9 to September 9; www.banksidegallery.com
