This is a Real Photo Postcard. Brothers? Possibly..or maybe friends. One of them is off to the war. I believe this is also a photo from 1917 to 1918..although this type of postcard a Cyko was only made during 1904 to 1908. Which means that either this gentleman was in the Military before WWI or the card was a left over and the photographer was using them up. This postcard has no identifying marks of any kind.
Thanks for stopping by, do come again:)
