This is an oleograph of Lord Rama (centre), Sita (right), Laxmana (left) and Hanuman (kneeling) by G.V. Venkatesh Rao, one of the most well-known artists who worked for the Ravi Varma Press.
Rama is the hero of the Ramayana, a Hindu epic poem. In seven books, the story narrates the exile of Rama to the forest with his wife Sita and his brother Laxmana, the subsequent abduction of Sita by Ravana (the demon-king of Lanka) and the rescue of Sita with the help of Sugriva - the king of the monkey tribe, and his minister Hanuman. After a fierce battle, the city of Lanka was taken, Ravana was defeated and killed, and Sita was rescued. Rama returned and was crowned to begin his glorious reign of Ayodhya.
The oleograph has been signed by the artist on the bottom right with "Bangalore" mentioned. The year is also mentioned, but hidden by the frame. The artwork is in very good condition.
