These two Bodhisattvas are similar in virtually all aspects, except for the images found on their headdresses. One image depicts a stupa, so the Bodhisattva is presumed to be Maitreya, and the other depicts a Buddha image, and therefore the Bodhisattva is presumed to be Avalokitesvara. Each Bodhisattva has a nimbus, wears a high topknot, and has a smooth and round face with long earlobes that touch the shoulders. Both figures wear long dhotis and stand in a tribhanga posture. The right hands hold whisks and in the left hands they clasp long-stemmed lotuses that grow up from the ground.
