Since 1994 Robert Sabuda has taken three-dimensional pop-up books to new heights. Elaborate dinosaurs leap off the page. Colorful Christmas trees rise up and blink. Knights in shining armor joust before the king and queen. The ease with which these things twist, turn, and delight readers is the result of much trial and error. Robert Sabuda is a completely self-taught pop-up book artist. Without any guidebook or mentor, Sabuda has always had to challenge himself to find out what is possible.
