Croydon modernist Sarah Wickens put me on to this amazing film of Croydon from 1965. It's Pathe newsreel footage showing gallery owner Nicholas Treadwell and his fashionable Art and Design shop in St George's Walk. It also shows him driving a double decker bus, his first mobile gallery, through the centre of town and out to the swinging suburbs.
Along the way we even get to see what East Croydon looked like before the building of all the towers, including the Thrupenny Bit.
Treadwell still runs a gallery in Vienna.
