Your office Christmas pictures - the winners

We have been delighted and astonished at the quantity and quality of photographs you have sent of your office Christmas celebrations. In this gallery you will find a selection of our favourites, from which we've also chosen six lucky winners, each of whom will receive a copy of The Guardian Year 2005 - a digest of the best writing in our paper over the last year. Click on the extended entry link to find out if you won - the word **WINNER** now appears next to the names of the six winning entrants. The competition is now closed. Thank you to everyone who sent in photographs; you have provided us with hours of entertainment.
