This is a Fenton Art Glass 4 1/2" vase from the yellow overlay line. This line was produced from 1948 to 1953. This is the #711 beaded melon vase that has a bright yellow interior with a white milk glass exterior. Fenton was marked only with a paper label at that time, so it is unmarked. It is in very good condition with no chips or cracks. Please email me with any questions.
