I am not disparaging the gentleman when I say that I saw him in Oman at least 20 years ago and he was in the early stage of some debilitating disease like Parkinson's and had a noticeable tremor in his hands. This obviously gave him some diffiulty with sketching and painting. I would have thought that by now he will certainly have given up art and may well, regretfully, have passed away. I shall be happy to be corrected if anybody knows differently.
