I Have a very old vase that my mom inherited in 1960. The vase is 19″ tall with 4 handles and a cream and green background with pink and yellow roses and green leaves on the front. It has AUSTRIA and the numbers 8448 on the bottom. I found a article that said AUSTRIA was on a lot of vases before 1914 or 1918. I cannot find another one like it. I am trying to find out what it is worth. HELP
