Created with Sparrow’s characteristic painstaking research and attention to detail, the walls of this Mayfair gallery are transformed into a fully-stocked chemist, handmade completely in felt. In this interactive performance-art piece each and every hand-painted artwork is sold straight off the felted shelf to customers who can purchase the full range of felt pharmaceuticals by the white-coated Sparrow herself.
