Michael Jackson fans have less just 24 hours to claim ticket refunds for the late singer's ill-fated comeback shows in London.

Fans can either claim their money back or opt to keep their tickets for the O2 Arena shows as souvenirs in lieu of their right to a refund.

Organisers AEG Live had already printed eight different versions of the £75 or £50 tickets before Jackson died in June.

The tickets, which feature a series of lenticular images, are expected to increase in value over time following the singer's sudden death.

It is not clear whether AEG intends to reveal how many of the 800,000 ticket holders have requested a refund.

The This Is It shows, which would have run from July until March 2010, had been set to mark Jackson's final performances in London.
