Celeb portrait sparks bidding frenzy

London, Jan 31: A self-portrait of popular boy band New Kids On The Block has sparked a bidding frenzy at a charity auction.

The caricature of the pop group at their recent O2 Arena concert in London was drawn by singer Donnie Wahlberg, who had managed to get the band to pen their signatures on it.

Wahlberg had apparently donated the A3-sized picture to the No Surrender Charitable Trust, which supports young adult cancer patients, along with the marker pen that was used to create the drawing, reports a news daily.

While the bidding for the portrait recently reached 1,060 pounds, the black pen, which "has been kissed and rubbed all over the body of Donny Wallberg", too has invited offers up to 255 pounds.

Successful bidders would also receive a video blog of Wahlberg at work on CD to prove its legitimacy as the auction comes to an end on February 4.
