Prompt
Create a realistic portrait of Ethel Roosevelt Derby, a woman from the early 20th century, dressed in elegant attire, with a subtle background that hints at her connection to the American Red Cross and her life in Oyster Bay, New York; she should be depicted in a formal, yet compassionate, expression, reflecting her work as a nurse and philanthropist, with a style reminiscent of classic American portraiture from the 1920s.
