The site further states that the current painting depicts a young prince dressed regally with a turban of South Indian style, characteristic of the court of Mysore. The style and treatment of both the figure and the background suggests that the painting was produced by an artist trained in the British academic style of the late 18th century. Furthermore, the rich clothing, the ceremonial dagger and the double string of large pearls hanging around the child's neck, identify the child as part of a princely family from South India. All of these elements combined with the striking features of the young boy suggest that the painting is likely to depict one of the sons of Tipu Sultan, who during the Mysore wars became popular subjects with British artists working in India.

What is the truth?
Below is the artwork painted by Robert Home who was an eye-witness of the reception of the Mysorean hostage princes. As you can see there are big differences between the princes in these two pictures.
Below is the painting of Raja Raj Krishna Deb (1782-1823), son of Raja Naba Krishna Deb, founder of Sovabazar Rajbari (Shobhabazar Royal Palace), Calcutta.
As the prince was born in 1782, he must be 12-13 years old in 1795. It is not known who painted it. Raj Krishna Deb's father Raja Naba Krishna Deb was the Diwan of Lord Clive and Persian Munshi to the Company.
