The subject of David Levinthal's latest work is a series of fine toy sets made in the 1950s by master toymakers Louis Marx and T. Cohn. These works, as always, explore the realm of chilren's play and imagination with a smartness that has made Levinthal such an important contemporary artist. Small Wonder is number four in The National Museum of American Art's American Scene series. The book design integrates elements from toy box art, assembly instructions, and the maker's logos and includes a fascinating essay by David Corey relating the toymaker's work to America in the 1950s.
