To celebrate Royal Mail's brand new 10:10 postmarks, we're giving away free 10:10 tags to the first people to submit a photo of themselves with a 10:10 stamped letter.

UPDATE: winning photos are already piling up in our inbox so you'd better be quick! Here are a few of our favourites from the 10:10 flickr:
