Complaint tablet to Ea-nāṣir

The complaint tablet to Ea-nāṣir (UET V 81) is a clay tablet that was sent to the ancient city-state Ur, written c. 1750 BC. The tablet, which measures 11.6 centimetres (4+9⁄16 in) high and 5.0 centimetres (1+15⁄16 in) wide, documents a transaction in which Ea-nāṣir, a trader, allegedly sold sub-standard copper to a customer named Nanni. Nanni, dissatisfied with the quality, wrote a cuneiform complaint addressing the poor service and mistreatment of his servant.
