I can't believe that I had the good fortune to acquire this gorgeous Van Briggle vase. It's in great condition; the glaze has the crazing of age, but no nicks, chips or cracks. Dating Van Briggle pottery is a job for real expert and I can't lay claim to being one!! I closely examined the base and the sparse marking includes the logo, "Van Briggle" and "Colo Spgs". The writing is small and not very deep. So someone who has specialized in pottery for years can explain it. All I can say with certainty is that it's genuinely old and I can't imagine it's a forgery, cuz, why? The glaze is amazing, and it's a real pleasure just to hold in your hands.
