Colour printed paper map 143x105cm. Good, neatly folded, rubbed to folds with creasing and foxing. Base information completed April 1960, revised October 1963, air information current through 22 November 1963, lithographed by ACIC 12-63. Roughly centred on Mecca, this is bounded by UAR Egypt, Sudan and Ethiopia (W), the Rub al Khali (E), and Yemen (S). This Second Edition dates to the early stages of the North Yemen Civil War (26 Sep 1962-70), that saw the deposed Imam Badr escape into the mountains on the Saudi border to raise a force among the Zaydi and seek Saudi support. He was also supported by Jordan and Israel, with the Republicans supported by Nasser's Egypt. The Saudi-Yemen border is drawn here from the Red Sea coast as far as Najran, beyond which the line ends with a large area labelled "boundaries in this area are undetermined". Colour tinted for altitude with contours, spot heights, notes and about terrain (with straight line labelled "limits of reliable relief" and areas labelled "relief data incomplete"); international boundaries; settlements of various size; rail, roads and tracks, etc. Aeronautical information includes different types of aerodrome (several marked abandoned or not usable), vertical obstructions with heights, and Prohibited Areas over Saudi cities with related warnings.…
