The Monsters of the Underground design came out of our contest asking for designs that repurpose a classic logo, and Jeremy Morrison mashed two icons together so well, we won't ever look at them the same way again. Most people on subways and metro systems and (in this case) Tubes don't think too hard about the fact that they're flying through past layers of their own city. Regardless of what you do or make every day, let this shirt be a little reminder that it's the stuff that stays underground that has the real lasting power.
