Antique Teplitz 19" vase with 4 handles, Amphora Works

Antique large vase with 4 handles, pink and yellow flowers, green leaves on a green and cream colored back ground.  Bottom has "AUSTRIA" 8448. I cannot make out the rest on the bottom of vase. Made around 1900 by The Amphora Porcelain Works. (1892- 1945). In the Teplitz- Turn area of Bohemia. I cannot find another vase like this or this large. I found 2 small vases that were similar but not the same.  This has been in my family for years and I would love to know the value.
