Not much to describe or research here. I asked a few people if there was another memorial and the half hearted replies gave me little hope of finding anything. I spent nearly an hour looking around - and found nothing. There is, however, a nice little monument dedicated to the Mill Brothers just a few feet from this flag pole.
This recording is the A side of V-Disc 521-A, published in 1943. It was one of hundreds of recordings created by American artists for distribution to GI's overseas during World War II and Korea.
