Amy Winehouse

The picture features the outline of the late singer's face, with the word "ladylike" next to it, and is expected to fetch between £50,000 and £80,000.

The painting is one of a number being auctioned by singer Pete Doherty - a close friend of Amy - alongside examples of his own work, which also feature paintings made with his blood.

Of his friend's portrait he said: "Amy was on the phone to her dad when she did that [painting]. She said, 'Dad, I'm with Pete and he's making me draw with my blood!' He didn't like me much, her dad."
