Chief Warrant Officer 3 Joseph Banks, installation postal officer and official mail manager for Marine Corps Base Hawaii, shows Soraya Henry, 3, a special postcard after her class finishes a tour at the base post office, Dec. 12, 2013. The postcard gives children a special website address where they can learn how to mail a postcard. The children from Kupulau Child Development Center received a mini tour of the base post office. They also brought holiday pictures to mail to family members. The Marines from the base post office taught the children how to stamp the official processing date on each letter and insert them into a mailbox. (U.S. Marine Corps photo by Kristen Wong)
