This 1975 issue from Türkiye Cumhuriyeti (Republic of Turkey) features the Kalkan (Scophthalmus maximus), also known as the turbot, a prized flatfish found in the Black Sea and Mediterranean waters. The artwork captures the fish’s distinctive diamond shape and speckled skin, set against a natural seabed background.

Printed by Ticaret Matbaacılık T.A.Ş., İzmir, the 75 kuruş denomination highlights Turkey’s marine biodiversity and fishing heritage. It is part of a beautifully illustrated series celebrating native fish species of Turkish waters — a favorite among thematic collectors focusing on marine life and fauna.
