An important artist's monograph on Thomas Bayrle, one of the most influential pioneers of Germany's Grey Pop movement in 1960s with Gerhard Richter. Early on, Baryle paralled Warhol with crude silkscreens, but soon moved into digital pixilation, some hand-done, some computer-generated. In the style of a more sophisticated M.C. Escher, Baryle shows his mastery of illusion, creating a series of portraits through thousands of tiny drawings of telephones, or hidden among a page of chain links. No English translation, but these mystifying images need no words to be appreciated.
