It's almost that time of year again when artists belonging to eight of the leading societies in the Federation of British Artists clear out their studios and bring their work to the Mall Galleries in London for the big clearance sale: Summer Madness. It runs from Wednesday 30 July to Wednesday 6 August. Grab your chance to buy a work of art by a leading British artist at a bargain price. All work sold can be taken away the same day. Admission is free.
