Soldiers Writing Letters Home, 1918

Even with the U.S. troop commitments abroad starting to wind down, there are still tens of thousands of men and women stationed overseas this holiday season.

Things have changed a lot since this photo, from the Smithsonian's National Postal Museum, was taken in 1918, but this is still a good time of year to think about making a donation to the USO.

What not hope over the USO donation site and send a little something?
