This photograph was probably taken by an amateur photographer and sent to the Photo Headquarters in Stuttgart, where it was developed and made into a postcard – a common practice when the amateur photographer did not have a darkroom available on location.
The postcard reads as follows:
7. June 1915 (Postmark June 7, 1915)
Dear Nurse Christine!
After a long pause, you, too, finally receive a sign of life from me, but in the field there is never much time to write. Thus, kindly excuse me. Here, a small photo with my good buddy, with whom I have already shared happiness and suffering and also a comradely bite to eat. And as the oldest in the battalion, we still feel anywhere from good to spry. Warm greetings from your cousin Ulrich Roller.
