                  were many attractions to entertain visitors of the fair. The 
                  "Zone" was a 65-acre amusement/concession area, 
                  with days' worth of entertainment. People could also visit the 
                  actual Liberty Bell (on loan from Philadelphia), have their 
                  fortune told by a gypsy palm-reader, take a ride in a biplane 
                  over the Bay , and see the day's news headlines typed out on 
                  a giant Underwood typewriter.
                There 
                  were thousands of exhibitors at the fair, from state and country 
                  exhibits, to manufacturing and production exhibits, to scientific 
                  and medical exhibits. Here is a bit of information on a few 
                  exhibits in the Palace 
                  of Varied Industries and photos showing the Hills 
                  Brothers and Sperry 
                  Flour exhibits.
                And 
                  at the end of the evening, visitors could enjoy one of the spectacular 
                  nightly fireworks presentations, while sampling foods from several 
                  coutries around the world (foreign cousine being being much 
                  harder to come by than it is in San Francisco today).
                 
                  There was so much to do at the PPIE, that it's not surprising 
                  how many people would return repeatedly during the course of 
                  the year to absorb as much as they could from the fair. (See 
                  example season ticket books.)
