Werner Schmalenbach, KURT SCHWITTERS (Harry N. Abrams, New York 1967)

"The purest exponent of the Dada spirit to emerge from Germany, if not from the entire movement, was Kurt Schwitters." I bought this monograph on Schwitters, with its 420 illustrations (including 54 hand-tipped plates in full colour) at a discount price from the Strand bookstore in New York in 1977.
