Very nicely designed book that documents a point in the urban planning process where aesthetic and utilitarian concerns were combined. More than 40 pages of text at front of book provide a solid history about manhole covers and similar utility covers, again, pointing out various aesthetic and utilitarian concerns regarding their purpose and design.
Further information, including locale and manufacturing dates and other details, accompany each of the hundreds of sharp and clear black and white photos depicting a dizzying array of covers spanning more than a century of United States history. Sadly, as the author points out, the current trend in manhole covers discards any artistic or aesthetic concerns leaving us with generic contemporary manhole covers. But that wasn't always the case as this book points out.
Besides the art of utility covers, this book provides insight into some of what is going on under the streets and sidewalks of America and what engineers had to confront in their task of making such things accessible. There's more here than you might imagine.
