The black velvet dress and pair of earrings worn by Whitney Houston in The Bodyguard along with other Hollywood celebrity memorabilia like Charlie Chaplin's cane will be up for bids at the Hollywood Legends auction in Beverly Hills, Calif.

From March 31 to April 1, bidders can snag iconic items from Hollywood and Historic Americana thanks to Darren Julien, celebrity auctioneer.

It proves a point that these items, they're an investment, Julien told The Associated Press. You buy items just like a stock. Buy at the right time and sell at the right time, and they just increase in value.

Two of the over 800 items up for bids belonged to Whitney Houston, who was buried on Saturday after she died at age 48, and some say it is too soon to give away her personal belongings to the next highest bidder.

It's a celebration of her life, Julien said. If you hide these things in fear that you're going to offend someone - her life is to be celebrated. These items are historic now that she passed. They become a part of history. They should be in museums. She's lived a life and had a career that nobody else has ever had.

Julien said the items, the $1,000 floor-length dress and $600 faux-pearl earrings, became available after she died on Feb. 11.

The dress and earrings are among the 800+ items up for grabs in the Hollywood Legends auction. Other items include Charlie Chaplin's cane, bowler hat and film-worn suit, Clark Gable's riding jacket from Gone With the Wind, Judy garland's tuxedo jacket from A Star is Born, Marilyn Monroe's platoons from River of No Return, Charlton Heston's robe and staff from The Ten Commandments and original movie posters from classic films like Casablanca and Some Like it Hot.

Bidders can bid in person at Julien's Auctions in Beverly Hills, Calif., where items will be placed on a public exhibition beginning March 19, or remotely online or by phone. The auction will be held over two days with two session per day, beginning at  10 a.m. PST and 2 p.m. PST on March 31 and April 1.
