Amy and Greg Newbold have opened a whimsical window into art history for the young reader: snowmen! Illustrator Greg envisions what it would look like If Picasso Painted a Snowman (Tilbury House, $17.95) (a cubist snowman, of course), as well as imagining snowy creations by Marc Chagall (bright, cavorting circus snowmen), Gustav Klimt (a cozy snowman family wrapped up in a highly geometric quilt), Grant Wood (Snowman Gothic), and eleven other masters. This goofy, immersive introduction to style, a boon to emerging artists and art appreciators, is topped off with an invitation to readers to develop a unique style of their own. Ages 7-10.
