Square jardinière and stand with river landschapes

Square jardinière and saucer of porcelain with spreading wall and flat rim, painted in underglaze blue. On the walls of the pot river landscapes with houses, trees, mountains and a figure at the water's edge; on the wall of the saucer bamboo branches; the rims with hatching. The pot has been broken; two corners missing from the foot. Blue-and-white.
