Beaded Melon Mini Vase, Fenton
Fenton's pattern #7151, these 4-inch tall vases are shown in their 1993 catalog in this blue as well as lavender, light smoke, and pink (as best I can tell from the photos). They're not often seen, even on eBay. This one sold for $16 on eBay in 2004--probably just about what they're worth.
