Egg & Spoon race - Abbassia Barracks - 1912 or 13 - Camel Corps sports day

This photo taken by my grandfather, H.T.Sutters, while working as an electrical engineer, installing electrical systems in Abbassia Barracks, near Cairo, Egypt, has been uploaded for the Vintage Theme Park's animal theme.
The reason I put 1912 or 1913 was that there were two of these tiny prints - less than a quarter of the size on this page - on my screen at least. One had 1912 written in pencil on the back and the other 1913. As they were definitely identical, it goes to show that dates on old photos can't always be relied on.
