This long-sleeve tee designed by Geoff McFetridge feels like a bit of a Threadless style design to me, and whilst I can’t quite make out the design completely, it looks like lots of words forming a tree, ipso facto, tree of knowledge.
It is also available in green with a white print, for those of you that have an aversion to white clothing (hey, some people do).
Costiness=$48 available from 2kshirts.
