Free free posters
They were each printed with an edition number on the back, and if you've got number 20616 then you've won a set of signed copies of the artworks.
But just in case you don't have that particular number, and perhaps didn't get time to go and pick up the posters, we've got a full set of them to give away to one lucky reader of this blog. They're not signed, but they're still lovely.
Just drop us an email before midday (GMT) on Friday 7 December, and we'll pick a name at random.
