Hi Andrea,
Thanks for the message but I'm no longer looking for Bird and Corn vases. Since posting I've manged to find a few and now have both a green example and an amber one in my collection (I am still looking for either a jade or opalique 2-Handled Rose Vase though...)
You should maybe post some pics in the marketplace though; it's a rare pattern and I'm sure there'll be several collectors looking to buy.
Best wishes,
Steven
