Laura McGee Kvasnosky, author/illustrator of the Zelda and Ivy books, visited Red Balloon Bookshop in St. Paul, Minn., last month, where she painted the store's windows with scenes from her latest book, Zelda and Ivy One Christmas. Kvasnosky also signed copies and read from the book. Red Balloon was one of five bookstores that won a contest sponsored by Candlewick Press; the four other winning bookstores are: Bank Street Bookstore in New York City, Eagle Harbor Book Co. in Bainbridge Island, Wash., Prairie Lights Books in Iowa City, Ia., and University Bookstore in Seattle.
