Eileen Mayo (September 11, 1906 to January 4, 1994), the British illustrator, was according to Jstor, famous for Her Prints, Posters, and Postage Stamps. Although her early work won prizes, she had to support herself working as a tutor. Marriage to Dr. Ralph Gainsborough, included a stepson who was 6 years old at the time, and a fresh security with which to pursue her art. Their home was in west Sussex, until after the war, and her access to nature there, encouraged her participation in an aesthetic movement which celebrated the English countryside.
Here is one of many book covers she did.
This is titled "Mother and Son" (1948)
There are more examples of here work here.
Eileen Mayo was a strikingly beautiful woman, and strikingly brave, to
maintain, as she did, that there should be no distinction between fine art and craft.
