Condition is acceptable: the cover shows scuffing, wear and creasing, and there is some foxing on closed page edges, the front and back inner covers, and a few internal page edges, along with mild yellowing. The binding remains tight, the pages are free of writing or dog‑ears, and the volume comes from a smoke‑free home.
