In four successive spreads, photographs of three animals appear on bright color fields, appropriately labeled. In the fourth quadrant, another photograph appears in a window, above a question; when readers slide the window up, the answer is revealed in the form of a repeat of its photograph. The format is beguilingly simple—“pig / hen / sheep / Which farm animal lays eggs?”—and it conveys a surprising amount of information in an interactive package bound to appeal to older babies and toddlers. The pages are unusually thick and sturdy, and the equally tough-seeming slide mechanics work smoothly, abetting use in little hands. Bright colors, clear pictures, simple science and a chance to put baby in the driver’s seat—if only it were longer. It publishes with two companions, Trucks (ISBN: 978-0-312-50704-6) and the bilingual Words/Palabras (ISBN: 978-0-312-50729-9). (Ages 1-2)
