Tracy’s interest in writing and illustrating for children began in high school when he wrote and illustrated several picture books to fulfill English composition assignments. In the 1990’s he began illustrating for textbook publishers and has worked for Harcourt Brace, National Geographic, Houghton Mifflin, Scholastic and Zaner-Bloser, among others. He wrote, illustrated and paper-engineered “A Visit to the North Pole” in 1993. In 2006, he was commissioned by Robert Sabuda and Matthew Reinhart to illustrate the New York Times bestselling popup book, “Castle” with text and paper-engineering by Kyle Olmon. Since that time, Tracy has been writing and illustrating books under the imprint, "Thar She Blows Books." Titles include "Balloon ABC" and “123 Anatomy” which feature animated elements on each page, as well as more traditional picture books such as “Mouse Builds a House,” “Nothing to Do!” and “Nobbin, Bobbin & Cobb."
