Charles Paine taught at the Blackheath School of Art from 1931 until 1940. He had previously worked with John Edgar Platt in Edinburgh and he gained his job in Blackheath through their friendship. Paine taught Commercial Art at the school, influencing many students, not least Meryl Watts (who in turn also influenced her teachers).
In the early 1930’s the art school was renowned for its teaching of Commercial Art. Many of Paine’s images feature in London Transport advertisements in the 1920’s -
