Thanks for the streams of photos! Well done, I have enough for a movie now!
They are all thumbnail size so I cannot see all the detail, but I can see enough to tell you what you have.
I am assuming the mark on the base is this one, correct?
Which is the mark for Victoria Schmidt, which the company used from 1891 to 1918.
Stylistically, this type of decoration and handle shape was typical of the period 1900 - 1910, which narrows the date down a little more. So your vase is well over a hundred years old.
Victoria Schmidt & Co began at Lazarus & Rosenfeld, Ltd in 1883 who sold to Franz Schmidt two years later. The factory was located in Altrohlau, Bohemia, which was then part of Austria. The same town today is called Stará Role, and the country is now the Czech Republic. It is located on the outskirts of Karlovy Vary (Carlsbad) about 80 miles due west of Prague.
Your vase is baluster shaped with elegant high arching & scrolled handles that join at top, terminating in an acorn finial, and all done in the Art Nouveau or jugendstil style. It has scattered flowers on one side and a figural scene from the classics on the other. The scene is a polychrome print (not hand painted) based on a painting called "Cleopatra" by the acclaimed Swiss artist Angelica Kauffmann (1741 - 1807). Here's a version of it on a very similar vase to yours:
XXXXX XXXXXffmann was a much copied and admired artist in the late 1800s. In fact she had more acclaim at this time, some fifty years after she died, and at the time your vase was made, than she ever did during her lifetime.
The vase is also elaborately decorated in gold, though I notice a good deal of the gold has rubbed from the handles which is going to reduce its value, I'm afraid.
If you were to see your vase for sale in an antique store it would have a retail value of $650.00. This is the replacement value and what you should insure it for.
Expect to get approximately 30% - 40% of this if you were to sell at auction or on line.
I do hope this helps!
Please let me know if you wish any further information, I would be happy to help.
And thanks for all your hard work and persevering with the photographs.
