New York-based auction house Sotheby’s is all set to auction a rare portrait of Sikh ruler Maharaja Ranjit Singh on March 24. Painted by celebrated artist Sobha Singh, the artwork has a reserved price of Rs. 2 crore. Art lovers in Punjab want the Shiromani Gurdwara Parbandhak Committee to stop the auction but the latter says it does not plan to do so.
