The Celebrated Jumping Frog of Calaveras County, and Other Sketches

Not applicable — the book predates book-club publishing. The reprint tells are (a) later Webb impressions of the same setting: no yellow advertisement leaf, and broken/worn type at pages 21, 66 and 198; and (b) the London piracies (Routledge 1867/1870/1872, Hotten 1870), identified by their own imprints. Beware supplied ad leaves and rebacked or resupplied cloth: verify the type points before accepting the ad leaf or the frog stamp.
