7" round low bowl in a matte blue glaze with a geometric line and dot pattern with breaks of double flower motifs - true Arts and Crafts design.  Made by Rookwood Pottery in 1928, production piece model #2160.  Stands 3" tall and probably used to have a flower frog in the center which resulted in some interior staining to the bottom from the residue moisture from normal wear and use.  The staining and a little craquelure to the glaze are the only flaws I found.
