While at the Ministry of Prophecies, there is a book in the top right corner with the name "Froud" on it, Brian Froud is the conceptual artist that worked on most of Henson's projects, and before his son was born he painted a picture of a baby sitting among goblins...after his son was born he bore a remarkable resemblance of the picture. Toby Froud starred as the "babe" in the final movie. This was explained in the making of and commentary on the DVD release of "Labyrinth".
