Artist's book by Broodthaers. Texts in German. "Before cutting the pages the reader had better beware of the knife he will be wielding for the purpose. Sooner than make such a gesture I would prefer him to hold back that wepon, dagger, piece of office equiptment which, swift as lightning, might turn into an indefinite sky. It is up to the attentive reader to find out what devilish motive inspired this book's publication. To that end he may make use, if need be, of select reading from today's prolific output. These pages must not be cut." -- from books inside covers.
