The 1926 Sesqui-centennial International Exposition held in Philadelphia featured many exciting and unusual attractions. One of the most fascinating was the elaborate gateway built at the entrance of the Exposition - a gigantic, 80 foot replica of the Liberty Bell. People, cars and trucks passed under it to enter the fair!  The sheet-metal Bell was covered with almost 26,000 15-watt light bulbs so that it could be seen at night.  Even the clapper was covered in lights.   The mammoth Liberty Bell was designed by engineers of the Westinghouse Electric and Manufacturing Company. The Giant Liberty Bell is depicted in this postcard and beautiful view book from the Sesqui-centennial Expo.
