Matthew Myerss career as a childrens book illustrator began in 2011 with two starred reviews: Publishers Weekly, which named him a Flying Start, and Kirkus Reviews, which said: "Myerss oil paintings truly amaze." Since then he has illustrated several books, including Clink, Tyrannosaurus Dad, A is For Musk Ox, Bartholomew Biddle and the Very Big Wind, and Battle Bunny. Rather than adapting each book to his own style, Myers prefers to adapt his oil painting style to best fit the idea of each book he is working on. He lives and works in Charlotte, North Carolina.
