I found this postcard of a group of soldiers taken in 1916, two years after WWI began.  It was among a group of photographs of Conrad and Lena’s.  I looked hard at enlargements to see if Papa was in it, but was never sure because he was not in every photo he owned.  When I had the message on the back translated I learned it was sent to Lena with the message: “I’m in this picture.  Can you find me?”  Armed with this information and more experience in seeing old photos of that era, I did find Konrad. Another pdf version of this story with other photos of Conrad and his sister Barbara is here.
