Cynthie Fisher. You should always be yourself! If you can't, the only thing to do is be a caribou! This Animal World design is printed on a 100% polyester men's t-shirt, and features the words, "Always Be Yourself, Unless You Can Be A Caribou, Then Always Be A Caribou" with an image of two caribou grazing on a mountain side. The dye sublimation process creates slight imperfections that are unique to each garment.
