Being one of many who grew up obsessed with Calvin and Hobbes, I immediately recognized this image of a bird from a Calvin and Hobbes strip. I rifled through my book collection and found the Sunday comic in “There’s Treasure Everywhere”. There is no mention of Watterson or Calvin and Hobbes on the webpage. The anonymous designer has simply lifted a drawing, rotated it and added an “edgy” spray paint thing. Here’s a close up of the T-Shirt:

An ideal situation would be to contact Watterson himself and notify him of this. The last thing I would want to see is the Universal Press Syndicate taking legal action leaving Watterson with nothing. I’m not sure how copyright and licensing works with syndicated comics. Apparently in some cases, the syndication acts like owner of the work and licenses it out for various profiting purposes that have little to do with the artist. I would hope that Watterson ratains the rights to his own work and has it all properly copyrighted.
