The Monterey Museum of Art currently has an exhibition called "Over Rainbows and Down Rabbit holes: 
The Art of Children's Books" and, reportedly, more than a few fairy tale illustrations are included in the exhibition.Overview from the website:
The exquisite artistry of classic children’s books is highlighted in this exhibition. View historic works by Beatrix Potter, creator of Peter Rabbit, to more contemporary illustrations by K.Y. Craft, Rosemary Wells and Maurice Sendak. The exhibition includes family activities and a family reading area.The Museum had the main event for the exhibition on August 21st which included sidewalk chalk drawings, recreating some of the illustrations on display.
Artist, Nikolas Larson, chose to recreate one of the illustrations from Paul Zelinsky's Caldecott winning retelling "Rumpelstiltskin". (Cover shown at end of post - click HERE to go to Zelinsky's website to read more about the book and see more of his amazing drawings.)
You can see more pictures of Larson's chalk 'painting' progress through the day at his blog HERE.Other pictures of sidewalk chalk drawings from the event can be seen HERE on the museum's Facebook page.The recreations are gorgeous. I don't envy whomever was tasked with destroying, er, cleaning afterward!
The Art of Children's Books exhibition is on display through September 13, 2009.
