This is a Bohemian art glass vase dating to the late 19th century, circa 1880 - 1900.
The vase is 8" high and 2 ½" wide at the mouth.
The glass is very light and delicate with a satin finish. The shape is cylindrical. The mouth is geometric, with eight sides, meaning the vase has eight interior panels, though in a round shape, and can be seen in an overhead photo shot as bringing depth and lightness to the color of the blue glass.
The front of the vase is all hand done, in white layered paste and enamel, the figure of a flying dolphin fish with a bare breasted lady sitting on top of the fish; the process was done on Bohemian glass and is called Florentine Cameo. There are splashes of gold enamel, and to the right a setting sun in gold, with ripples in gold below the fish. The artist creates the impression that the fish is flying above the water as the sun is setting on the horizon. At the bottom are some gold flowers, perhaps to indicate that the fish is near the shoreline.
There is a band of enamel at the top rim.
The rim is polished flat. The pontil is deeply indented, round, and polished smooth.
There are some letters etched into the bottom but I can't make them out.
There are no chips, nicks or cracks, though the white enamel at the top does cover a few tiny indentations. There are a few small spots of discoloration on the white painting on the front of the vase.
