Fantastic two-page fold-out pop-up in rear, in perfect working order, complete with dangling movable monkey and 2 separate movable pieces showing each boy at foot of a tall palm tree which can be inserted in several places in the scene. There is a 7 page story to accompany the pop-up and a full page of coloured illustrations of 24 jungle animals. Plus illustration inside upper cover in 2 colours, all illustrations by Voitech Kubasta. Vojtech's Panascopic Model Series were presented in the same format; a single story bound in illustrated heavy triptych boards, the back covers unfolding to reveal pop-ups standing as high as 25 centimeters. Vojtech's work is among the most highly sought after in this genre. Slightly worn at extremities, but overall VG++.
