According to the Library of Congress these are a couple prints based on paintings by William Bauly. The Union flag painting could be based on a post-Sumter painting by Frederic Edwin Church. Both works were deposited for copyright on September 6, 1861. There’s something about them that made me consider putting them up for September 11th.
