James E. Buttersworth, signed, c.1850. We do not know which ship Buttersworth painted here. The United States Navy never had many warships of this size and not all existed when Buttersworth was painting. The most likely candidate is the USS OHIO, which left New York in June 1847 to transport David Todd, U.S. Minister to Brazil to his post in Rio de Janeiro. This was just about the time when Buttersworth first came to this country. Buttersworth added three schooner yachts to the painting, both for interest and to increase its marketability. One flies the flag of its owner.
