This paper comments on two Mesopotamian bricks belonging to collections of the Asia and Pacific Museum and the National Museum in Warsaw. Both bricks bear cuneiform inscriptions. The first was fashioned during the reign of the Ur king Amar-Suen (c. 2046–2038 BC) while the second is to be dated to the reign of the Neo-Assyrian king Shalmaneser III (858–824 BC). They commemorate building projects commissioned by these two Mesopotamian kings.
