Norwalk CT: Easton Press, 1981. Hardcover. Unpaginated preliminaries (including Winterich's wonderful appreciation), 346p., hardbound in 9.5x6.5 inch boards covered in reconstituted leather gilt-decorated. Sparks contributes an energetic color frontis portrait of Twain and scattered b&w sketches thereafter. A perfect copy, purchased when new and never handled til now.
FYI, the John Winterich intro makes certain that you will never again speak of THE Adventures of..a habit-vulnerable misstatement and mistake, one that our Eastoners make here.
