Vintage Cubist Inspired Dog Ashtray or Planter

A geometric black and white pooch sits guard over this vintage ceramic ashtray. Marked “Made in Japan,” it is either from the 1930s or 1950s, before or just after Japan was occupied. The cubist inspired, art deco feel makes me think it is 1930s. Crazing to the glaze, but no chips or cracks. Some discoloration inside. Looks great at a mini vase or planter. Dog is 4 1/8” tall, vessel is 2 3/4” high. 3 1/2” deep, 4 1/4” wide.
