I've also found another illustrator, Petrov, who drew up Last-Minute Fashions, which were supposedly airmailed from London by Mary St. Claire (this was during the War, so Paris was out of the question). Petrov's illustrations are a little more static than René's, but still quite charming.
My favourite by far though, are the illustrations of Dorothea Johnston, about whom I can find nothing. She usually illustrated the feature Mary Hordon's Paris Notes, which was written by the fashion editor about the latest couture clothing from Paris. I love the way she uses sweeping lines to give the clothing a feeling of movement. Everything looks so glamorous! The spread below is from 1952. Don't you love the blue sunray pleated dress with the black spots? It's Dior, of course!
