W.H. Coltharp had a problem. He’d been asked to build a bank in Vernal, Utah, but the bricks he needed were in Salt Lake City, 127 miles away. Wagon freight would have been too expensive, so in 1916 he sent 15,000 bricks by parcel post, essentially mailing the bank to Vernal.

The post office was not delighted with Coltharp’s ingenuity. Postmaster General Albert Sidney Burleson wrote that “it is not the intent of the United States Postal Service that buildings be shipped through the mail” — and he set a new limit of 200 pounds per day per receiver.
