Below left: A wall in my Hall - SYMMETRY: a Teddy Millington-Drake abstract painting, two Chinese baby pens [yes, babies once took the place of umbrellas and sticks]; a high Baroque English stool painted cream and highlighted in dark brown and upholstered in John Stefanidis Flowers fabric from the Japanese Collection.
