The Pigman

Harper issued a library/institutional binding under the Harper Crest imprint in pictorial boards without a dust jacket — this is not the trade first and is commonly offered as a first edition; ex-library markings and the absence of an issued jacket are the tells. The key reprint trap is post-1969 Harper printings that retain the "FIRST EDITION" statement while adding a number line at the end of the book or on the copyright page. Harper Trophy, Bantam, and Dell paperbacks are reprints.
