If you've been to a bookstore lately, you've seen copies of Robert Sabuda's Winter's Tale stacked high. The initial print run was 250,000 copies, giving evidence of how popular his pop-up art is these days. Sabuda is a paper engineer, and he talks about his craft in an article in the Winston-Salem Journal. I like his point of view:
There's greater attention to children's books now as a backlash to the technology in kids' lives. Parents feel the need to give an alternative to all the media saturation.
The author/illustrator's web site is chock full of information about the art form, including a bibliography and directions about how to make your own.
I was curious about how public libraries handled these books, with their enticing (for little fingers) art work, and in an unscientific survey of five local libraries with good-sized collections, I found that four reserved Sabuda's pop-up books for reference/in-house use only and one carried other Sabuda titles but not the pop-ups.
