Rest Time in the Life Class (1923). Dorothy Johnstone (Scottish, 1892-1980). Oil on canvas. City of Edinburgh Council.

A rare depiction of life at the Edinburgh College of Art, in which the artist - the teacher herself - appears in the background, touching up her work. At 16, Johnstone enrolled as a student at the ECA. She took the Life Class with Ernest Stephen Lumsden where she revealed her talents at informal portraiture. In 1914 she became a member of the staff at the ECA.
