One of the country's most controversial sketches is back up for auction.

A drawing of the Beehive with Helen Clark's signature first sold at a school fundraiser in 2001 for $80.

However the former Prime Minister has refused to confirm or deny whether she drew the picture.

It was sold at auction for $4000 in 2007, and is now on Trade Me for $11,000.

There haven't been any bids yet, but the auction has attracted over 2000 views.

The auction closes tonight at 10.35.
