These soldiers were tasked with sorting through the holiday mail for U.S. military personnel in 1944, during World War II. Delivering mail during the war was a big job. Postal officials would publicize the best times to send a package overseas, as well as box-packing tips. On the homefront, friends and family were encouraged to send mail to their loved ones as letters were known to boost morale. What have you received in a care package from a loved one? 📷 @nationalpostalmuseum」7月13日 23時58分
