This is one of the original versions of this Le Jan classic French Art Deco fish. Made by the Saint-Amand-les-Eaux factory and offered for sale by the ManuFrance company in the 1920s - 1930s, many subsequent versions and colours have sold over the years.
With a good LeJan signature and in a very pale pink craquele glaze.
It should be also noted that this is the larger version (as I believe all the original ones offered for sale were), at around 12” (30 cms) tall.
In great condition, a sought after French Art Deco ceramic sculpture
