This monograph serves as a catalogue for a 1990-91 exhibit traveling throughout Europe and the United States. Page after page demonstrates the Bechers' fascination with the variations (and similarities) possible within given structural types. On one page we see 18 different "industrial facades;" others show us 9 different "gas tanks," 9 different "post-war houses," 9 different New York City "rooftop watertowers." A fascinating book.
