This vibrant 0.40 Franc stamp from Guinea showcases the brilliantly patterned Goldfasan (often known as the Golden Pheasant Killifish), rendered in vivid shades of red, blue, and turquoise. Issued as part of a thematic series celebrating freshwater fish, it captures the species swimming above aquatic plants against a warm yellow background. The crisp typography and deep violet border give it a striking 1960s–1970s design style typical of Guinean wildlife issues. A desirable piece for collectors of ichthyology, African fauna, and topical fish themes.
