All you need to do to enter, is tell us what you'd love to see on a London Underground T shirt. It can be a slogan, roundel, picture of your favourite Tube station, image of Bob Crow or whatever you like!
We Admire can't promise to make the winning T shirts, but it will give them more inspiration for future designs. Keep an eye on their work through their We Admire's Twitter account.
Good news is that you don't have to be based in the UK to enter. We Admire will kndly send the T shirt wherever you live in the world. We'll select three winners at random, but please make sure you leave a name in the comments so we know who you are. Anyone who shows up as Guest or Anon won't count.
You have until 11.59pm UK time Sunday 16th January 2011 to enter and we'll announce the winners next week, so don't forget to come back to see if you've won! Have fun & good luck.
