This is a classic water jar by Robert Tenorio.  The jar is painted with wild spinach (black) and red clay slip.  The jar has a wide, sharp shoulder and a short neck.  There are cloud and rain designs around the neck. At the shoulder are cloud and circular sun patterns.  The style with the various squares, lines, and circles are all indicative of classic Santo Domingo pottery.   The jar is signed on the bottom side in the clay, “Robert Tenorio, Santo Domingo. Note the big dipper pattern, which Robert also etches into the designs of all his pottery as part of his signature.
