BEVERLY HILLS (AFP) - A hotly anticipated auction of Michael Jackson memorabilia will go ahead as planned, organisers vowed Monday, as they lifted the veil on a treasure trove of items from the eccentric pop icons Neverland Ranch. Martin Nolan, executive director of Juliens Auctions in Hollywood, said that despite legal action from Jacksons production company seeking to halt the April 22-25 sale, the auction would proceed. Were extremely confident that the auction will go ahead and were very proud of the exhibition that weve set up here to show off these items, Nolan told AFP at a press preview of the sale. Jackson lost the first round of a legal challenge earlier this month, when a Los Angeles judge dismissed an attempt to have the production companys contract with the auction house declared invalid. A second court hearing, where the company is seeking an injunction to halt the sale, is to take place on Wednesday. MJJ Productions claimed in a Los Angeles Superior Court lawsuit filed last month that certain priceless and irreplaceable items due to go under the hammer April 22-25 had extraordinary sentimental value.According to MJJ Productions, Juliens was asked to take some goods from the house for sale, but these could not be put up for auction until Jackson had given his final consent to the inventory. Meanwhile, Nolan said his company was expecting a flood of interest from members of the public as they prepare to hold an exhibition of the 1,390 weird and wonderful lots that are to go under the hammer next week. Were expecting to have a lot of people here, said Nolan. Were aware of people flying in from all over the world Asia, Russia. The vast collection, including items such as Jacksons iconic, jewel-encrusted glove and a customised Rolls Royce limousine featuring an interior finished in leather, walnut and 24 carat gold are among the Aladdins Cave of mementos from Neverland which Nolan said could raise between 10 and 20 million dollars. Jackson has not lived in the ranch, which is set on a secluded and sprawling estate in countryside north of Los Angeles, since his acquittal in 2005 on charges of abusing a minor at the property. Jackson is currently preparing for a series of comeback concerts in London in July. Tickets sold out within hours when they went on sale. Nolan said next weeks auction represented the end of an era for Jackson. What were doing with this exhibition is celebrating Michaels life and career to date, Nolan told AFP. The auction of Neverland represents the closing of a particular chapter in his life. Spread out across several halls on the site of a former department store, the Beverly Hills exhibition of Jackson items going under the hammer give a rare insight into the pop stars former life at Neverland. Extraordinarily elaborate costumes, antique furniture, lifesize statues of superheroes and Star Wars villains, from Batman to Darth Vader, and a fully equipped computer game arcade are among the lots. Its a very diverse sale theres something for everyone in the sale from trains to castles to limousines, Nolan said. The glove is the most iconic piece, this speaks to Michael Jackson and its something that everyone knows. Its estimate is between 10 and 15,000 dollars. But it could easily sell for something in the region of 100 to 200,000 dollars. Nolan said entering Neverland for the first time last year to begin appraising items had been like entering Xanadu the vast estate featured in Orson Welles classic movie Citizen Kane. It was amazing to see what was there 1.8 miles of train track, two trains, two train stations, a lake, the main house, the office, the game room, guest cottages, it was just a treasure trove, Nolan said. It was his Xanadu. And he walked away from it all.
