These are 2 large artworks, framed under glass. There is no provenance or information on the back. They belonged to my late father and my Japanese step-mum and were purchased, I believe, in the late 70's, early 80's in Japan for a lot of money at the time. Any information you can give me on the artist (well-known in Japan, I believe) I would be grateful. As well as an indication of their value now.
