From Publisher's Website:
When not busy being a certified lecher (Just look at his drawings!), Andrew works in his spare time-- at least the last eight years of it-- as the primary author, illustrator and chief executive of Studio Cranium. Andrew's career started (well, sort of) when he was chosen to produce illustrations for a small role-playing game publisher... which unfortunately went out of business before he could draw anything for them. He has played role-playing games since the second grade, which may have arrested his mental development and would explain his steel trap-like mind-- rusty and illegal in 37 states! It is believed that this has led to his peculiar fascination with fluffy elves and extremely large cars. Commonly known as "Captain Cranium" or "HED" due to the 24-inch circumference of his skull. Some suggest this is due to some sort of radiation accident at birth.
