Is this mystery skin-bleaching cream sold on eBay the secret behind Jacko's white face?

But the secret behind Michael Jackson's skin 'problem' may have finally been discovered after a fan put his skin whitening cream on eBay.

Before and after: A black Michael Jackson in his Jackson Five days, and the modern day Wacko Jacko

The world's most prolific collector of Jacko memorabilia has put this and a number of other items  -  seized by the police as evidence after the singer was arrested on suspicion of child molestation  -  up for sale on the auction website.

The seller, whose username is 'vaccaro99' has put up a starting bid of $25,000 (£14,000) and in the item's description claims that a former employee of the singer, who authenticated the items, said Jackson, 50, would have cases of the cream to hand.

Also included in the sale is a letter explaining why Jackson wanted an annulment from Lisa Marie Presley, again with a starting bid of $25,000.

There is also a handwritten note from the star to his late sister-in-law Dee Dee which he penned during his four-month 2005 trial, which has a starting bid of $10,000 (£5,700), and a 'Do Not Disturb' door sign from Neverland  -  with a silhouette of a small boy sitting in a circle.

That is on sale for $5,000 (£2,850), the same price as a 'never-seen-before' photograph of Jacko with a young boy on his lap, both dressed as cowboys.

The seller does not say how he came by the items.
