Link: Biggest Post Office to be built in Chicago
(The news first came out in August, 1931.)
CHICAGO is to have the largest post office in the world. The fifty-acre, twelve-story building will be completed and ready for occupancy within about a year and a half, according to a recent announcement of the United States Post Office Department. It will be able to care for the 19,000.000 letters a day expected by 1943, in addition to the parcel post packages and newspapers.
