From the Southwestern Americana Collection Scottsdale AZ we have a 1970s Maricopa Black on Buff Geometric Bowl - Alma Lawrence, measures 7''W x 4''H, indented directional handles, polychrome black on buff with red burnished inside, signed on bottom by artist Alma and Maricopa, ''traditionally hand built with native clay, stone burnished buff slip is painted with mesquite sap and wood fired, Alma Lawrence is known to prefer the buff colored slip. Artist Bio: Of all the potters active during the twentieth century, Alma Lawrence's vessels are probably the easiest to identify. The designs on her pieces are unique and stand out from the work of other Maricopa potters. Rarely using the solid elements that tend to dominate most vessels, the designs are composed of tightly grouped, thin-lined units that connect and flow into each other creating a continuous design band. The designs on each slip are separate and clearly divided by a thin black line; however the layout is done so that it creates the appearance of a single band of decoration_x000D_.''
