The
Sesquicentennial International Exposition marked the 150th anniversary
of the signing of the Declaration of Independence and the 50th
anniversary of the 1876 Centennial Exposition. To advertise the expo,
the Post Office Department issued a new 2¢ Liberty Bell stamp. In fact,
one of the fair’s main attractions was an 80-foot replica of the bell
covered with 26,000 light bulbs!
John Wanamaker had helped plan
the Centennial Expo and conceived the idea for the world’s fair in
1916. At that time, Philadelphia had gained a reputation for
political corruption and Wanamaker believed that a world’s fair could help improve how people saw the city.
