The publication of this book is the result of an extraordinary event -- the 1997 discovery in Blossfeldt's estate of sixty-one previously unknown collages, in virtually mint condition, of photographic contact prints arranged on large cardboard sheets. Blossfeldt apparently used these to study the relation and similarity of the photographs and to compare them graphically and aesthetically. On some Blossfeldt had made marks or handwritten notations. Others show lines for cropping. The collages, published here for the first time, unveil a hidden treasure of modern photography and cast fresh light on the systematic approach Blossfeldt used in his photographic studies. All collages are reproduced in four colors.

Introducing the book is an essay by Swiss art historian Ulrike Meyer-Stump, a contributing curator to the exhibitions at the Kunsthaus in Zurich.
