While scanning my prints I came upon this interesting photo of a GN boxcar. I found the faded original in a file when I was assigned to the Coast Guard District 11 headquarters in Long Beach. I presume that these are Coast Guardsmen, the photo is from the Los Angeles harbor area, and was taken during WWII.
