Large Goblet - Glass Vessel Painted With Enamels. Late 19th Century

Large goblet - glass vessel painted with enamels.
Late 19th century.

Painted glass with vegetable and floral motifs with enamels in multiple colors, with gold decorations.
There is one flaw that is not noticed, but becomes apparent upon closer inspection: a surprising element is missing. (see indicated with arrows in the photos)
Foot decorated with glass spheres.
Beautiful object, in hand-blown glass, which represents the eclectic taste of the second half of the 19th century.
