Nice interview with Sendak this a.m. on NPR. He discusses his new book Mommy? Sendak has been a pop-up book collector for years.
Questioned about his "themes," of children in jeopardy, Sendak responded:
..[that is] the only theme that I have. And it's also a view that sometimes got me into serious trouble as a younger artist. You know... now that I'm old...you know...they treat you like Helen Keller when you get old. They aren't as angry at you for doing odd things.
Mommy? is being billed as his "first" pop-up book which makes me hope maybe more are to come?
