This pretty little Mini Bud Vase was produced by The Fenton Art Glass Company in Yellow Overlay. This line was made from 1949 until 1953. but this color was made only in 1950. These were made as part of the Tiara Line. All items in the yellow overlay with the yellow on the outside are considered to be rare, and were all made in the #711 Beaded Melon. My pictures make it appear that the vase is white at the bottom. Looking at the vase, it is completely yellow. I'm not sure why I can't get a picture of a completely yellow vase. I have tried with and without a flash, but the vase is yellow on the outside. The vase measures about 4" tall and is in very good condition with no chips or cracks. Please email me with any questions.
