This beautiful 0.30 franc stamp was issued by France in 1963 to commemorate the Floralies Nantaises, a prestigious horticultural exhibition held in Nantes. The design showcases a vivid array of flowers in red, blue, and green, including tulips, roses, hibiscus, and hydrangeas, symbolizing France’s rich botanical heritage. In the background, the Château des Ducs de Bretagne in Nantes is finely engraved, adding cultural and historical depth to the theme. Created by Pierre Gandon, this stamp highlights the elegance of French engraved issues and remains a sought-after piece for both floral and thematic collectors.
