Above an example of Hannelore's work, a print reminding me strongly of the image of British actress Joan Hickson (1906-1998) in her role as Miss Marple.
Mrs. Hickson, in later, life resembling in looks and in posture closely my dear late mother in law.
Joan Hickson played Agathe Christies (1890-1976) detective in full color for many years after legendary Dame Margaret Rutherford (1892-1972) did for years in the age of black & white.
As it happens Henriette Grimm illustrated a 1924 book: "Tanz, Jugend, Gluck" (Dance, Youth, Happiness) with "original" lithographic prints and etchings, it would be interesting to know what exactly is inside the book.
And Googling I even managed to find some more examples of Henriëttes art.
