That's right it's a fantastic London Underground Map Pencil case and I'm going to throw in a London Transport Roundel pencil too. I can see you all trembling with excitement as I'm spoiling you so much. The pencil case actually makes a pretty cool make-up bag or small wash bag as it's waterproof.
Anyway, when you first look at the case, you may think it's a pretty fair representation of quite a bit of zone one on the current Tube Map. However, on closer inspection (here's a larger version) there are a number of things wrong with it. So to enter, please tell us what is wrong with it. Just give one thing only (anyone giving more than ONE thing or making two guesses will be disqualified) and you must each give a different answer - so speed is of the essence here. As usual leave your email address or website or blog address in the comments below to enter. You have until Sunday 5th February 23.59 GMT to enter. All correct entries will go into the Neil paperclip selection and the winner will be announced on Monday 5th February.
