This is a classic polychrome jar by Blue Corn.  Blue Corn began by making black-on-black pottery, but it is her polychrome pottery that makes her the most famous.  This jar is polished with a white clay slip and then painted.  The piece has sixteen wide feathers as the design around the neck of the jar.  The ends of the feathers (near the rim) are painted with green clay.  It is signed on the bottom in the clay, “Blue Corn”.  It was originally purchased in the 1980s.  It is in very good condition with no chips, cracks, restoration, or repair.
