cartographer into the 1950s with her work published by the
Sunday Observer and reproduced in the
Sunday Herald in Australia. She is best known for her commercial British art-deco style, although did also work in more naturalistic designs. The cover designs she created for British editions of books were often retained for the American editions, too, a rarity at the time she was working. Her work is now considered very collectible. Her later career was affected by ill health, but she continued to work in illustration, even when unable to leave her bed. Some of her later work was illustrations for greeting cards. == Personal life ==
