Amber Libbey Glass

Vintage 10 ounce tumbler measuring 3 1/2 inches in height. I have never been able to find this particular floral pattern by Libbey and wonder if someone decorated the glass to match their dinnerware. I originally had 6 of these glasses with this handpainted design but at this point can only find 3. There is little sign of use. They are priced individually. I need your zip code to calculate the postage. If anyone knows if this is an official Libbey pattern, I would appreciate any information.
