The official exhibit opens Wednesday and includes one of the late singer's Rolls-Royces, some of his trademark gloves and sequined jackets and a contract from his early days with the Jackson 5.
It is timed to coincide with the release of a posthumous album and a movie consisting of rehearsals for his ill-fated "This is It" comeback performances in London.
The sold-out shows were canceled after Jackson's sudden death in June.
The exhibition at London's 02 Bubble arena includes more than 250 items from Jackson's personal estate. It includes a crystal-studded hat and other items never before shown to the public.
