Here’s a shot of my 64 vases. Left to right, we have 64C, 64D, 64A, 64B, 64E. In 1964 catalog, the B vase has a much more exaggerated lip, rising to a point on one side. The B in my photo with the double split lip is more usually found. In the 1965 and 1966 catalog, only B, D and E are shown; in the 1967 through 1971 catalogs, only B and D. I’m working off the 1962 – 1971 Pina book of catalogs, so it is possible there are pages that show the other vases in the intervening years.
Have a wonderful day,
