Enameled ceramic empty pocket

I offer you this superb decorative enameled ceramic pocket emptier representing a stylized fish in bright colors: blue, red, yellow, green and white, on a speckled midnight blue background. Slightly curved shape and softened edges, typical of the design of the 1950s/60s, probably artisanal work or from a European artistic ceramic workshop (Vallauris influence or Bitossi style). In good general condition.
