Professional Photographer

I have uploaded a picture in photos of a portrait of a junk.It is mounted and signed presumably by the photographer. It was likely taken in the 1920s and probably in Hong Kong.The junk has a serial number on the bow which may help date it and locate it. The photographer's signature is undecipherable at least to me but mybe someone here has some knowledge that could identify it. The picture was in the posession of my cousin whose family ( Donnelly)  resided in Hong Kong in the 20s but were previously in China.
