I have been lucky on this occasion, this artists daughter sent pics of both of these to her dad and he has confirmed that they are both his, now I have the fun of selling them, he is a well know south africian artist, but may be not so well know in this country, I have to sell them as they were given to me to sell in my charity shop, so I think a visit to the auction house is necessary.
I would never had thought of contacting the artist before, but thanks to a reply on this I was given a contact web address,
these forums are great help to the likes of me, who is not very knowledgable
