This is a reverse glass painting, most likely from Maharashtra. According to a description of the painting published on page 76 of the book βReverse Glass Painting in Indiaβ by Professor Anna L. Dallapiccola:
βProbably made by the same hand or atelier as Gajendramoksha, this painting shows the mighty Pandava hero Bhima, whose characteristic weapon is the club. He was the son of Kunti and Vayu, the wind god, and hence the half-brother of Hanuman. Huge, violent, and prodigiously greedy, he plays a conspicuous role in the Mahabharata. His arch enemy was the Kaurava prince Duryodhana, with whom he fought bitterly during the Mahabharata war. Set against a red background, Bhima's mighty frame is compressed into a frame too narrow for his superhuman strength and power. In his right hand he wields his huge club, ready to strike the enemy. He is dressed in a short lower garment with an angavastra thrown over his shoulders. He also wears a crown and the usual jewellery, and a conspicuous Vaishnava namam is drawn on his forehead. The reddened corners of his eyes reveal a fiery nature, and a bushy moustache grows on his upper lip. The yellow foreground provides an effective backdrop for his flexed legs. The top and sides of the painting are enlivened by a draped curtain.β
