Science Fiction vs Literature

I adore this image. Love, love, love it. I found it via this Wordsy post. But I’m having trouble tracking down the name of the illustrator to attribute it properly. If anyone can help me track down the original source I’d appreciate it. This is the kind of lovely image I wish I could find at Threadless.

UPDATE: The lovely Peter has chimed in to let us know that the illustrator of this marvellous image is Tom Gauld, who illustrates and publishes at Cabanon Press. I have just spent 20 minutes on the site looking at Tom’s other work and, oh, how I love it so! Go check it out and buy things. Thanks Peter, and kudos Tom!
