(Piano not included.) 

Yes, you can win this specific poster. Partly because it's Christmas and I'm feeling generous, but mostly because I went to London's @MouthTapedShut preview screening of David Fincher's very awesome film and accidentally picked up two posters on my way out.

If you would like to win this accidentally-acquired leftover super-amazing (probably) limited edition Dragon Tattoo poster, simply email This e-mail address is being protected from spambots.

Send your answers by 22:59 Monday 19th December (that's tonight). A winner will be picked at random.

Please include your postal address (UK only, ta) and your Twitter username, and who knows? If things turn out well, Santa might well dump the poster on your doorstep before Christmas Eve.

(Note: You cannot exchange the poster for a cash prize of £2.50, or whatever the Royal Mail delivery cost for a poster is.)
