Artists-Potters exhibition Mansard Gallery Heal’s

Very rare 1930s poster by Nicholas de Molas for the Mansard Gallery in Heal’s Department Store.
The Mansard Gallery was established in 1917 and held exhibitions by Modern British artists, Vorticists, Group X and Modern French artists such as Picasso and Matisse.
British artists that designed posters for Mansard Gallery include William Roberts, Edward McKnight Kauffer and Paul Nash.
The poster is linen-backed and framed in plain black wood frame and UV plexi. I can remove it from the frame.
