An Indian friend emailed me this image and told me it had been painted by the father of his classical Indian singing teacher. I remembered having seen the actual painting somewhere in India. A bit of internet research reminded me where:
Glow of Hope, alternately titled "Woman With the Lamp", is a painting by S.L. Haldankar. The work is currently stored in the Sri Jayachamarajendra Art Gallery at Jaganmohan Palace in Mysore, India.
