Grosset & Dunlap.
Copyright 1959. Never revised, so the original 20-chapter text and art. This is a 1978 printing, Farah-coded 1978A-31.
There's a yellow bar across the top of the book, but it's NOT a glossy; it's one of the last matte picture covers of this title.
Excellent condition. Black/white multi-scene endpapers. Blue-inked top page block. No writing/markings. Tight, square. Opens as if never read.
Lists to Mystery of Crocodile Island on the rear cover.
