“Pages, Mages & Macrophages” is a science fiction/fantasy book club for the employees of Arrowhead Pharmaceuticals in Madison, Wisconsin. They were preparing to read book number 42 (if you understand the significance of that particular number, you are my people), and wanted a shirt to celebrate. So how do you combine microbiology and fantasy literature? With a group of macrophages having their own book club! I love the way this shirt turned out, and it was a big hit with the book club members.
