This necklace features a 1946 French postage stamp from the Air Post with Mythological Themes series depicting Iris goddess messenger of the Gods. The image was taken from a real, used, vintage postage stamp and may have post office cancellation marks. The size of the pendant is 20mm and the chain is 18 inches long, in a matching antique bronze finish with a lobster clasp. Pendants are water resistant but not waterproof, I recommend removing before showering, bathing or swimming.
