Throughout their careers, Greg and Tim Hildebrandt would work together and separately, and together again, winning awards, fame, and challenges as illustrators. They would create everything from the world famous poster for Star Wars, to the best-selling calendars illustrating J.R.R. Tolkien’s The Lord of the Rings, to their own fantasy novel, Urshurak. They would also work on advertising art, hundreds of classic children’s books, and the covers of numerous fantasy and science fiction novels. Together they have won the coveted Gold Medal from the Society of Illustrators. In 1973, the Child Study Association chose their Giant Panda Book as a Children’s Books of the Year.
