Ludwig von Mises Institute 作者： Blast89

For mises.org. The book is an edited bit of clipart from fotolia, and the caduceus is from some school health site (did I really need to mention that?). The coat is released (by me) under a CC-BY-SA-3.0 licence by Charles Richard Clark II, a Mises Institute Librarian. The parchment is stock, from Empty-dreams on deviantART: http://empty-dreams.deviantart.com/art/Parchment-38523655
