San Agustin Blue on White is a fino (fine grade) majolica within the Puebla tradition, and overlaps with the fino Puebla Blue on White examples identified by Florence and Robert Lister. It is distinguished from Puebla Blue on White by its white (rather than off-white or cream-colored) background, its dark cobalt blue paint; and it’s complex design layouts. The lobe designs typical of Puebla Blue on White are less common on San Agustin Blue on White.
