The lack of exhibition record of north African subjects prior to 1910 suggest that Annan made this image later, most likely not long before 1925 when views of that region were exhibited in Glasgow at the Scottish International Salon of Photography. A note on Annan’s letterhead to Stieglitz as stated 17th of December 1924 inserted in catalog 55 indicates the date this group was presented to him, pointing toward they’re being recent work. [1]
