Angus Peter MacDonall, who came from Saint Louis, USA, where he studied at the Saint Louis School of Fine Art, was one of the early group of artists who settled in Westport, Connecticut, to make it a famous art colony. Angus was especially popular with fellow illustrators because of his three beautiful daughters who were in great demand as models.
Angus was a prolific illustrator of American life, often with humorous, home-spun themes. Angus MacDonall illustrated for most of the magazines including Scribner's, Harper's, American, and The Ladies Home Journal. For several years he did a regular double spread illustration of human interest or social commentary for the old Life magazine. He also did the cover for the Saturday Evening Post, October 8, 1921 edition.
A frequent contributor to advertisement campaigns, notably for Jell-o - in 2001, a painting he did for that company auctioned for $9,350. His three daughters were also in demand in the illustration world, but as models, not artists, as they were all beautiful.
