Computer-enhanced photograph of a bowl on display in the Museum of Fine Arts, Boston (item number 13.5083), illustrating Wallpaper group "pmg". According to the Museum of Fine Arts, Boston this bowl is from Kerma, around 1700-1550 B.C. The Museum of Fine Arts, Boston states about this object: "Fired Clay, Kerma, Eastern Deffufa (K I), 1700–1550 BC (Classic Kerma Period) Harvard University–Boston Museum of Fine Arts Expedition: 13.5083

The running-spiral design on this pot is reminiscent of motifs used on pottery and other objects in the Aegean and Eastern Mediterranean during the mid-2nd millennium BC. Its closest parallels, however, are to Egyptian pots of the Second Intermediate Period (1700–1550 BC). Yet the vessel was clearly made in Nubia, using Nile clay and Nubian forming and firing techniques. It suggests greater Nubian knowledge of Egyptian material culture during this period, perhaps derived at least as much from spoils of war as from trade.

An undecipherable inscription incised on the vessel may represent a local potter’s effort to imitate Egyptian hieroglyphic signs, or it may be an attempt to spell a name or word in the language of Kush." http://isaw.nyu.edu/exhibitions/nubia/highlights.html#
