I have been working with Sanshee
and Riot Games
and we will be representing League of Legends with two t-shirt designs at PAX Prime this year! This is one of them, featuring one of the heroes Twisted Fate.
The other shirt features Teemo! If you're going to PAX be sure to stop by our booth and pick up one of the shirts! We're very excited to be able to bring these and represent Riot Games. We also have some surprises for people who purchase one or both of the League of Legends shirts from us.
Here's a picture I took of the TF shirt: [link]
