PLYMOUTH (AP).- As people get ready to celebrate the royal wedding of Princess Diana’s son William, a collection of her gowns, stories and videos about her life is going on display in New Hampshire. The exhibit “Diana — The People’s Princess” is being featured at The Common Man’s Flying Monkey Movie House and Performance Center in Plymouth starting Monday. It ends May 8. It showcases some of her most well-known gowns, which she auctioned for charity just weeks before her death in 1997. Among them is the ink blue silk velvet dress she wore to the White House State Dinner in 1985 when she took to the dance floor with John Travolta. The exhibit has been shown in Branson, Mo., last year, and in Orlando, Fla.
