To Kill a Mockingbird

US J. B. Lippincott (Philadelphia, 1960) is the true first; the UK first (Heinemann, London, 1960) is a separate first that follows the US. The signature jacket point is the Truman Capote-credited author photograph on the rear panel — Capote took the photo; he did not contribute a blurb (the flap blurb is Jonathan Daniels). Lee rarely signed; authentic signatures are scarce and frequently forged, so provenance is essential.
