large old Asian water color

I bought this out of an old mansion, the woman that lived there was 93 and told me she remembers this painting hanging in the living room back in the 30's, it very large about 4 feet by 3 feet including frame, the artist sounds american or english (Lynne Hugh) can't find any info on the artist. Any one see any others like this, seems to be painted on some kind of cardboard stock. The frame has chipping and seems to be black lacquer. Just would like to know if it's worth more than I paid and if so, where to sell it.
