NY, Harper & Row, (1970). The uncorrected proof copy of the first American edition of the Nobel Prize winner's masterwork. This proof copy is in the very fragile "padbound" format, which presumably accounts for its extreme scarcity: padbound proofs, because of the way they're constructed, tend to lose their front or rear covers over time. This is a near fine copy. This proof differs from the published edition by the inclusion of a review of the Spanish language edition of the book. [#911037] SOLD
