Behind modern collage he's a long history of Oriental pasted papers for calligraphic picture-poems, of folk art and primitive mimetic magic, and of amateur handicrafts. Since before World War I, however, collage has been linked with innovative art and social movements the witty and lyrical Cubist collages of Braque, Picasso, and Gris, for example; or the Futurist "representations" of time, motion, and sound of Balla, Boccions, and Carra; the moralizing obscenities of Grosz, leveled at postwar corruption in Germany: the psychological probing of Ernst and Schwitters in Dada and Surrealist context; the mockery of Marcel Duchamp. The reaction of fifty or more years ago, when such strident novelties font assaulted the public eye, was even more clamorous than that accorded to Pop and Op in the 1961. The author, Dr. Harta Wescher, was the friend of many Bauhaus and other collage artists. A critic of international reputation, she co-founded the Paris periodical Cinaise. Her writing embodies the enthusiasm, humor, afternoon and personal comprehension of a participant in the lively and contentious circles she frequented. Assiduously she tracked down reminiscences and forgotten works from those tumultuous times, rescind from oblivion much previously on published material.
