Photo from Robin Maugham's book - "Journey to Siwa" made in 1947. These are the first images that I found after the end of the war and they show us a still traditional Siwa but we are close enough to our times to recognize places and, perhaps, people.

Campbell in his book describes his journey through the Italian Libya in 1931 and 1932 which leads him to pass by the oasis of Siwa coming from Jarabub. It doesn't say anything new about Siwa and its surroundings (but it does provide photos from 1932 including one from El 'Areg Oasis)
