A two day auction scheduled for later this month in California will offer costumes and other memorabilia from the estate of the late Grammy-winning singer and actress Whitney Houston. Heritage Auctions said highlights of June 24-25 sale in Beverly Hills will include Houston's 1986 Emmy for her performance at the 28th Annual Grammy Awards, which is expected to fetch $10,000, and her personal script for the 1995 film "Waiting to Exhale," which could sell for $1,000. More than 100 pieces of memorabilia will be included in the sale, which is part of the company's Entertainment & Music Signature Auction.
