As previously noted on this blog, king Abdullah I of Jordan (1882-1951) was a keen chess player, having invited Moshe "Mendel" Marmorosh to play with him in Amman in the 1930s (see also Edward Winter's chess notes #4211.)
Above is another photo of him from 1941 -- at the time, he was the emir (governor) under the British mandate. This photo appears on "Mr. Chess"'s very interesting picasa album. (Hat tip: Andrew McMillan).
