Whether your blood type is A, B, AB or O your ailments will be instantly cured if you could have a mythical creature as your blood donor as represented in the Unicorn Blood Transfusion T-shirt by John Tibbot. Available in either a hoodie or a short-sleeved shirt, Tibbot's design is perfect for those who never did receive that unicorn they begged for birthday after birthday.
The design on the front of shirt is of a medical pouch filled with rainbow-colored blood, so even the most squeamish will have no problem sitting down for this transfusion.
Unlike blood type O, which is the universal donor, U+ blood is only appropriate for fantasy-oriented individuals such as gnomes, griffins, big foot and leprechauns. However, should you venture into Narnia I'm sure an exception will be made in the event of a medical emergency.
