An unidentified postal worker sorts the mail at the main U.S. Post Office at 1102 A Street in December of 1948. The bins are piled high with holiday mail. The Tacoma Post Office expected to increase the number of postal employees from 475 to nearly 1,000 during the busy holiday season. Typically about 200,000 letters were handled daily, but this would increase to about 700,000 letters daily at the peak of the holiday season, roughly December 17th.
