Between Worlds: The Art and Design of Leo Lionni opens at the Norman Rockwell Museum in Stockbridge, MA, on November 18, 2023. Leo Lionni (1910-1999) was a key figure of postwar visual culture, who believed that a smart, pithy design language could unite people across generations and cultural boundaries. He first achieved success in the field of graphic design, serving as the influential art director of Fortune magazine from 1948 to 1960 and personally executing such innovative designs as the catalogue for the Museum of Modern Art's seminal photo exhibition The Family of Man. Then, in the 1960s, he embarked on an equally groundbreaking career in picture books, using torn-paper collages to illustrate modern animal fables such as Frederick and Swimmy, which are still beloved today. But even as his books won multiple Caldecott Honors, Lionni--who had begun as a painter--also maintained a fine art practice centered on his Parallel Botany, a richly imagined world of fanciful plants. This volume, the catalogue of a major exhibition at the Norman Rockwell Museum, is the first to present Lionni's extraordinary career in the round. Written by leading scholars and with an introduction by the artist's granddaughter, it is illustrated with abundant examples of his work, including many little-seen items from the Lionni family archives. Leo Lionni: Storyteller, Artist, Designer will be an important, and eye-opening, contribution to the history of art and design.
