Pitman, New York, 1968, 3^rd pr., BCE.  Hard cover, 189 pages.  Good plus; spine ends bumped with a bit of sunning at top edges; binding sound with a very slight lean.  Dust jacket shows some edge and cover wear, a few stains.  Upper corner of front end paper (1.5 x 2.5”) torn away; remainder of interior clean and unmarked with occasional age spot.  ‘Children have a natural style of learning, Holt says, which is warped or destroyed by later training. … is an incisively written, compelling call to the adult world to understand how children learn … and to do something about it!’ (from flaps)
