From Kotaku:
Now, we have something to sweeten the deal. Bethesda will also be giving the winner of our Paint-An-Egg-Contest a Vault Boy Fallout 3 shirt. There’s more! The back of this shirt is signed by Fallout 3 team. So big kudos for Bethesda for pitching this in and for the devs for writing their names!
Let’s paint some eggs then. More info about the contest here.
