St. Nikolas, Santorin (Greece)

Very hard to know the exact age of this B&W card. It was mailed and has two stamps, with almost-legible postmark, a caption that either reads “1999” or “1939,” and reference to Joakimides Thira. It has been pinned to a bulletin board several times at top but the holes are well hidden on front. Serrated edges. Grade: 4
