These were passed to me from a grandparent over 10 years ago.  I do not know how she came about getting them. There are three pieces total.
First, excuse the pictures. I will try to explain the coloring the best I can along with sizes.
The larger vase is semi-gloss. It begins with a slight yellow color at the top, cream in the middle and a mauve color along the bottom. Each color, gradually fading into each other. It is approximately 16-18 inches in height. The floral pattern is similar on each side except the flower colors change. You would see a single pink flower on one side with muted green leaves. The other has muted green leaves and with two flowers – one yellow in color, the other cream. The shape inside is a straight down hole; approx. 2 1/2 inches in diameter. The top opens as pictured, into an oval mouth. Dimples shown inside are where the handles meet. Side view is approx. 1 ½ inches wide, rounded to front/back.
The smaller vases are semi-gloss. The color pattern begins with Mauve on top, cream in middle and a very very slight hue of blue - grey on the bottom. Each color gradually fades into each other. It is approx. 8inches in height. The floral pattern is similar on each side except the flower colors change. You would see a single pink flower on one side, then two flowers on the other – one yellow flower and the other cream. When facing the vase from the side, the shape inside, is the same, including the top mouth.  The dimples seen inside are where the handles attach. Side view is approx. 3-4 inches wide, rounded to front/back.
- Looking first at both of the smaller vases. On the bottom of the vases, there is raised lettering: (on top) Hull Art – (in the center) U.S.A. – (on bottom) W-4-6 ½  On both vases there is a deep hand etch that is a Z or 2Â
- Looking at the larger vase: On the bottom of the vase, there is raised lettering: (on top) Hull Art – (in the center) U.S.A. – (on bottom) W-15-10½ (the 15 could also be 13). There is also a deep hand etch of a Z or 2. A second deep etch of a J or 1 – if turned upside down, both ways reads the different letter/number because the way it is etched/written
Input would be great. Not sure what the history is with our family, but would be interested to know value, sales-ability or heritage (if any!). Thank you for your input.
