Print Liberation is at it again (it being making cool shirts). The design isn’t complex at all, it’s just simple elements combined excellently to make a quality shirt.
I also like it because it’s not super in your face, as some “green” shirts can be. It’s a good design first, and a political message second (at least in my interpretation).
You can pick this design up for $22.00 at Print Liberation. Unsurprisingly, it’s printed on organic shirts.
The biodegradable cycle preferred by Lance Armstrong.
You can tell because he uses those same awkward triangular tires in races just to prove how awesome he is.
