AMUSEMENT PARK- Willow Grove Park - Airship & Mountain Scenic Railway -  PA © 1906:   Willow Grove Park was an amusement park located in Willow Grove, Pennsylvania (the part which is in Abington Township), United States, that operated for eighty years from 1896 until the 1975 season. It was generally an alternative to the Woodside Amusement Park in Fairmount Park until its closure. The park operated under the name Six Gun Territory from 1972. After closure, announced in April 1976, the park sat vacant until the land was cleared for a large shopping mall known as Willow Grove Park Mall, which opened in August 1982. The mall pays homage to its predecessor by displaying banners and other objects which hark back to the land's days as an amusement park; a merry-go-round built and installed in 2001 operates within the mall.  The park originally was conceived by one of the three Philadelphia area traction companies, the Peoples Traction Company, as a means to encourage weekend customers on the trolley line, a practice that led to the coining of the term trolley park. Willow Grove was one of the premier amusement parks in the United States for a long time, until it was eclipsed by the openings of Disneyland and other more modern theme parks beginning in the 1950s.  This Undivided Back Era (1901-07) postcard shows the Mountain Scenic Railway, which offered a "circular tour of the Alps, under roaring waterfalls, through cool dark tunnels, and a thrilling toboggan ride."  The card is in good condition but shows some edge wear.  W.
