Those flags with their  bright red disks on white silk were just like the one I found with my father's possessions, after he died, in an envelope with one of his letters home from combat in Luzon and wrote about in my memoir, The Souvenir. These flags on display in the darkened gallery are the centerpiece of an unusual exhibition called “A Peaceful Return: The Story of the Yosegaki Hinomaru” at the Columbia River Maritime Museum in Astoria, Oregon.
