The Diary of a Lady’s Maid is (not — see below) the first American Weekly cover series by Fish (Anne Harriet Sefton, nee Anne Harriet Fish), running from August 17 to October 26 1930. Her lovely work graced this Hearst publication several more times over the ensuing decade, including 1938’s Awful Week-Ends.
In this series, Fish uses the device of a maid’s diary entries to tell of the ridiculous excesses and adventures of a particularly rowdy British upper-class family, the Tumwaters.
EDIT: Mark Johnson alerts me to an earlier Fish series, Social Advice from Aunty Climax, from 1928. Thanks Mark!
