PY/Miyao is most well known for their kitchen items that were made to look like bright and cheery veggie people and anthropomorphic fruit faces.  Manufactured from the late 1940's through 1961, these cheerful pieces of pottery provided much needed relief from the gloominess of WWII. The irresistible cherubic smiles and enormous, laughing eyes of the heavily glazed series gained enormous popularity throughout the United States.  The nautical sets they made were a pair of fish, several mermaids, and a family set of seahorses that included a mom, dad, and baby seahorse.  The colors on these nautical sets are most vibrant and the attention to detail is just wonderful! The fish and seahorses have rhinestones for eyes.  The mermaids have wide, child-like eyes.   PY is the only manufacturer that made these sets.  There was no variation in colors, they were always painted as in the pictures provided.  There have been plastic and ceramic molds made of the pink/green mermaid sister wall plaques above, the seahorses family and the fish so individuals can paint them.  The ceramic molds of the sisters above are pretty true to the size and shape, but the plastic molds make them a lot fatter and a blocky tailfin.  There are no mass produced molds of the two on a shell and the swimming one below.  The ones on the shell are actually wall pockets so you can place a plant in them.
