I came across this painting for sale on Ebay several years ago and at that time I did not know that G D Thyagaraj was the brother of Paul and Arulraj. I probably would have purchased it had I known. It had some damage in the form of foxing and the photograph shows some reflection on the glass.
It is similar to one by Paul Raj in that it shows a man keeping watch on his fields. I was told that this kind of platform is called a "Machaan". It seems to show a sunset which has been captured very well. I hope you like it.
