Organizers say a first-of-its-kind exhibit of Princess Diana memorabilia will go on display near Los Angeles on the historic ship the Queen Mary.

The Press-Telegram says "Diana: Legacy of a Princess" will include hundreds of items from the British royal family and will showcase more than 2,000 artifacts, featuring gowns worn by the princess, letters, designer sketches and other items.

Many of the items have never been displayed, including a garden bench that was a wedding gift for Prince Charles and Princess Diana

The exhibit in Long Beach will be co-hosted by the ship and the nonprofit breast cancer awareness organization Pink Ribbons Crusade. It's scheduled to open June 16.
