The paintings featured on the stamps are: At the Theatre (1928) and Rollande (1929).
In order to select paintings that would be representative of Heward, veteran stamp designer Helene L'Heureux thoroughly explored her large and varied body of work. "Almost immediately, her figure paintings stood out as her most significant pieces," she says. "At the Theatre and Rollande exude a sense of great depth. They seem to give expression to the difficult position of women in the modern world - a difficulty that's carried into every sphere of social life."
