The interior color of this two-part bowl rim sherd cannot be determined. It's a mottled interior, with browns and grays. Although the surfaces now appear only to have been smoothed, I think, judging by polishing traces on the top of the rim, that the vessel was one polished. The rim is unusual. It's continuous and two part, with a point at the top interior side of the rim, one axis that slants down and outward just a bit beyond the interior extent of the body.
