Final answer:
The image of 'Henry James, 1910' is indeed Henry James and not James Joyce, his lover, or an unknown person. This identification of the person in the image is supported by the descriptive information provided from the source.
Step-by-step explanation:
The person depicted in the image described as 'Henry James, 1910' via Bain News Service and available on Wikimedia Commons in the Public Domain cannot be James Joyce or his lover as they are different individuals. Henry James was a prominent American-British author known for his novels and short stories, whereas James Joyce was an Irish novelist and poet, renowned for works like A Portrait of the Artist as a Young Man. As the archival image is explicitly named after Henry James, the correct identification is of Henry James himself. Other images mentioned, such as those of Ernest Hemingway, Kate Chopin, Emily Dickinson, and the artistic figures described, are of different individuals or fictional representations used for separate discussions or artistic interpretation within their respective contexts
