Five thousand aerial perspectives of cities were published during the nineteenth century, so the more than 100 reprinted here in color constitute the cream of the crop. The images, created by itinerant artists, reward both an aesthetic sense and, in close-up viewing, a historical sensibility for urban growth in the post^-Civil War decades. The latter applies more to the largest cities, of which bird's-eye views were made over time, which allows observation of the advent of railroads, factories, and large parks, such as Golden Gate Park in San Francisco. Every small town's demand for a perspective view of itself sustained the market, and such places (Bismarck, North Dakota, to name one) in the resultant drawings sometimes look like nothing more than a street grid, a courthouse, and a few houses and stables. Thus, views commissioned on the basis of civic pride carried a promotional purpose of attracting new citizens to the vacant lots--whereas we can enjoy them as quaint visual time capsules. A pretty work for pleasant browsing. Gilbert Taylor
