Despite a heavy rain, the New York Times estimated that 200,000 people traveled to the stadium located on the festival grounds to hear President Calvin Coolidge officially open the Sesquicentennial Exposition on July 5, 1926.  After speeches by both President Coolidge and Mayor Kendrick, the President attended a luncheon and then visited Independence Hall, Christ Church, and Camden, New Jersey. Various other celebrities and political figures would visit the Sesquicentennial over the next month.
The rain that plagued the opening ceremonies, however, would continue throughout much of the Exposition. For a variety of reasons, the Exhibition failed to make a significant amount of revenue and faced extreme financial difficulties. Eventually, several vendors brought legal action against the Exhibition for lack of payment and the entire festival was placed into equity receivership by the United States District Court on April 27, 1927. 
The Philadelphia City Archives contains a collection of print images taken of the Sesquicentennial. Many of the prints were removed from scrapbooks several years ago and stored in archival quality boxes to prevent deterioration and fading of the images. The prints are now in the process of being digitized and placed on PhillyHistory.org. Including photographs of everything from the construction of the Sesquicentennial grounds to an Industrial Parade underneath the Liberty Bell replica to a variety of athletic events, the Philadelphia City Archives Sesquicentennial Collection provides stunning images of events that captured the attention of the City during the summer of 1926.
