The Khyber Pass, 1936/7.
A large panoramic photograph of the Khyber Pass, produced by the British Army for issue to the artillery posts guarding the 'North-West Frontier'. Overlays for the photograph were issued (not present) which identified and labelled various locations in the pass. The overlays could be periodically updated by military intelligence. Using the overlay and photograph, commanding officers were able to clearly identify target locations when instructing remote gun placements to open fire on the transient enemy forces. Composed of two photographs joined at the centre, overall image approx 20cm x 182cm, recently mounted, framed and glazed at considerable expense.
