A viewers comment from the GS message board
To me, the picture looks very clearly like a double exposure. The clarity and detail of the images makes them a little too good to be true. Behind the two men you see what looks like a sign that doesn't look like part of the trench background. If they were true apparitions there would be no background. Based on their attire they appear to be WWI German POWs. The man on the left has what appears to be the letters P and O on his shirt or jacket. If they're German POWs then the lettering is consistent with the standard military practice of painting the letters POW or PW on their uniforms to identify them as such. The cap worn by the man on the right unmistakably resembles the WWI German army field cap with its two cockades (the round insignia devices) and colored band.
