The guy who designed my book found this photo in my collection of documents from the Beale Papers at the Library of Congress and liked it:
I seem to remember “Newport” written on the back of it, but couldn’t find much more about it. Beale had family in Newport, Rhode Island, and sometimes spent time there. I’m afraid I don’t know more about Beale’s Newport connections, or this photo. Very possible Marie took it as she liked photography. If anyone has any other information, please let me know.
