I really like this, almost as much as I like your 'A History of Western Philosophy. With Owls" which I am still bitter at threadless for not printing and still live in hope that it may, eventually, somehow, be printed. Um but yes, I really like this, except for the colour. Maybe if it was a grey owl with a purple or green or red sweater on, maybe if it was a black t-shirt. Hmm. But anyway, please design more awesome owl t-shirts, your illustrations are fantastic :D
And if only that History of Western Philosophy. With Owls tee could be printed, I might die happy :)
