The first American postcard was developed in 1873 by the Morgan Envelope Factory of Springfield, Massachusetts. These first postcards depicted the Interstate Industrial Exposition that took place in Chicago. Later in 1873, Postmaster John Creswell introduced the first pre-stamped "Postal Cards", often called "penny postcards". Postcards were made because people were looking for an easier way to send quick notes. The first postcard to be printed as a souvenir in the United States was created in 1893 to advertise the World's Columbian Exposition in Chicago.
