Thank you for submitting your item for appraisal. This appears to be a painting on cotton fabric depicting the marriage of Rama and Sita. Sītā or Seeta, is the consort of Lord Rama ( an incarnation of Vishnu) and an avatar of Sri Lakshmi, the Hindu goddess of good fortune and prosperity and happiness etc. The painting depicts a powerful couple within the Hindu religion, such paintings are therefore quite popular and easily available. The estimate is based on similar late 20th century paintings offered or sold at auction.
