I wish I were a botanist so I could identify all of Gallé's flowers, but unfortunately I'm not. The flowers look like clematis, but I don't think they are. What's special is the windowpane technique used to keep the flowers blue. Otherwise the yellow background would mix with the blue flowers, making them appear green.  It's a lovely vase, 5" tall x 6½" diameter.  Signed in cameo on the side.  Mint condition.
