Yes, very nice, very rare and I am very fortunate to have acquired a pair. I could find only one other vase of this type engraved in the leaf and daisy [pictured], it resides in the Brooklyn Museum. Seems to be at least a handful of variants.
Some examples in the Corning Museum: Engraved leaf and daisy by accession number. 50.4.186, 50.4.263, 50.4.254a & b, 55.4.47, 94.4.9,and 99.4.82
Differently Engraved vases of the same type by accession number: 50.4.255, 50.4.256, 55.4.53, and 55.4.270
