A bit of a mystery which I found crumpled up in a flea market bin. An incomplete pencilled note on the back reads "no. 10 camels carrying to Jamboal.....". It has been suggested that this last word might be a variant spelling of 'Yambo al Bahr' or 'Yanbu al Bahr', which is on the Red Sea in present-day Saudi Arabia, and that this is part of the 10th company of the Imperial Camel Corps during the first world war campaign against the Ottoman Empire.
I count 12 camels.
