In 2001, excavation of perimeter wall  was extended to the Northwest. Here the surface of the wall is being cleared and the bricks outlined. Note the excavation in the foreground left where there was no mud-brick.
Although neither of these specific molded terracotta tablet pieces comes from Trench 11, four less well preserved examples from the same mold(s) were found in debris outside of the perimeter wall in that area, clearly establishing a second half of
