Photographer Mark Identification "Egyptian"

Would anybody be able to identify this photographer by his or her mark on the photo. Got it along with some prints of Egypt by Gaddi & Seif. This photo is the only one there was. Measures 11.75" x 9.5". Any help will be greatly apprteciated.

 

Lehnert & Landrock

From Wikipedia:

Lehnert & Landrock was a photographic studio run by Rudolf Franz Lehnert and Ernst Heinrich Landrock active in Tunisia and Egypt in the early 20th century, noted for producing Orientalist images. Rudolf Franz Lehnert and Ernst Heinrich Landrock produced images of North African people, landscapes, and architecture for a primarily European audience. These images were mainly distributed in monographs, though also as original prints, photogravures, and lithographic postcards.

today criticised as sexist - understandably to some extent. but during Victorianism and Orientalism highly en vogue in smoke rooms to be shown around.
to check if it's a one off copy of some value you might contact a museum:

Gaddis & Seif have an interesting company history as well because they were non-European.
