A series of 12 double spreads showing dwellings at different periods, prehistoric to present, with brief explanatory text. This useful informational book is distinguished from others on the topic in two ways. Testa's illustrations, while not quite as outstanding as those in his recent Wolf's Favor, use bold design and serenely brilliant colors which lend clarity and beauty to the conventional sequence through mud hut, Renaissance palace, etc. And he adds a diverting touch: each era sports anachronistic details--TV antennas on a castle, popsicles in biblical times, a bicycle in 18th-century Amsterdam. Only the title page warns of these ""surprises,"" which should spark entertaining, mind-stretching conversation with class or individual.
