It was proclaimed as such to honor a Roxboro native who died on board the Titanic.
Oscar Woody died while trying to save the mail. He was one of five sea postal carriers killed that night.
Monday, at the Titanic artifact exhibit in Raleigh, a commemorative envelope was unveiled and dedicated in Woody's honor.
A special postal stamp recognizes his efforts, and several of his belongings are part of the exhibit at the Museum of Natural Sciences.
