Large Canvas 1950 - 1960 ... Young Mother & Her Child In A Street In Hong Kong ...signed?

Large and interesting canvas from the 1950s-1960s depicting a young mother carrying her child in a Hong Kong street: a label on the back mentions a sign "Man Fong Picture frame maker," a canvas merchant located at 41 Wellington Street in Hong Kong. - The work is signed in the lower right corner, but the signature is difficult to decipher / cliché details - Note: it is an ink or gouache painting, that is to say, a work executed with a single color, diluted with water. There are preparatory pencil lines visible here and there: the Chinese calligraphy in the background corresponds to the signs that were in the streets of Hong Kong at that time... - it should be noted that technically, there is a very high level of skill evident: for the last twenty years or so, there has been a real enthusiasm for Chinese and Indochinese painting from this period, and identifying the signature can sometimes reveal an excellent artist / a tip for those interested in research. Canvas size: 60 cm x 45 cm - minor damage to the canvas, without affecting the quality of the work / ask me for more photos if needed -
