This fresco depicts two naken children wearing a belt and boxing gloves. Their head is shaved, excepted two long locks on the back, and two shorter on the forehead. Their dark skin indicates their gender. The boy at left is more reserved, and wears jewelry (bracelets, necklace) which indicates a high social status. Work from the same artist of the Antilops fresco. Room B1, building B in Akrotiri.
