Three books belong in this section: "A Girl in the Art Class" (1927), "On a Paris Roundabout" (1927) and "The London Roundabout" (1933). Extracts were published in magazines of the time, such as Blackwoods (e.g. "Gradus ad...Montparnassum" in Blackwoods, March 1929, 412-421).
Cora Gordon also had a memorable encounter with Édouard de Max, considered, with Sarah Bernhardt, one of the greatest actors of his time: http://janandcoragordonart.blogspot.com/2014/09/jan-and-cora-gordon-de-m-for-edouard-de.html . A number of other Paris acquaintances are mentioned in "Three lands on Three Wheels": in the "Closerie des Lilas, where before the War we used to make merry on Tuesday nights with Paul Fort, André Salmon, Picasso, and all the lights and lesser lights of the Modern Art Movement."
