Dusseldorf: Art-Press Verlag, 1970. First Edition. Quarto. SIGNED by Bernd and Hilla Becher (in Bernd's hand), and briefly inscribed: For Diana [Jannetta] / from Bernd and Hilla / Dusseldorf 14.12.79." Jannetta was involved in securing a show for the Becher's in Pittsburgh. The manifesto of the Dusseldorf school: a group of Becher students, loosely affiliated, comprising some of the big names of today's art world, including Andreas Gursky and Thomas Struth. Like Ruscha, the Bechers blur the line between documentation and art, creating an almost scientific polemic that transcends any preexisting medium. (Parr / Badger, v2, 261; Roth 194-195; Open Book 258-259; Auer 518). Three corners gently bumped, else near fine in an almost near fine jacket with closed tear at the top of the front panel, and a small crease at the bottom right flap fold. While copies of this landmark title have become more available in the past five years, signed examples - especially from Dusseldorf - remain uncommon.
