The picture shows this 1944 World War II Serviceman Christmas Photograph From Burma. The other side is blank. This looks like it was created to send home as a christmas card to the family. It pictures a serviceman with a pipe (I guess this is Nate) and reads:
Burma 1944 Seasons Greetings Nate
It measures 4-3/8" x 3". It is in excellent condition with some light wrinkling.
