It's a celebration day! I added to my Laos stamp collection, my main collection, a set of four Sunken Die Proofs (SDP) in monochrome signed by artists of the set about Lao folklore issued by the Kingdom of Laos on May 20, 1966. Stamps were all designed by Sa-Nguan Rodboon and each stamp was engraved by different engraver:
Here are the proofs in high resolution. I scanned the central area of each:
Ordination of Monks, Engraved by Robert Cami
Sand Stupas building ceremony, Engraved by Georges Bétemps
Religious procession with a Phassad Pheng, wax stupa model, Engraved by Charles Mazelin
