Occupied Japan - baby pigs in a pen - S&P shakers

Let me hear the aaaawwwwwws! This delightful three piece salt and pepper shaker set is a pair of piglets in their pen - trying very hard to escape. These were made in Occupied Japan (sometime between 1947 - 1952). Both piglets are marked Japan and have their original stoppers. Their pen is marked Made in Occupied Japan. Approximate measurements - pen is 3.5 cm high X 7 cm X 4 cm (1 3/8” X 2 3/4” X 1 5/8”) - piglets are 6 cm high (2 3/8”).
