Dolphins Vase
While these are marked WG, implying Westmoreland, I can find no reference to them in Lorraine Kovar's books on Westmoreland. They show up in amethyst on eBay, mostly by sellers who specialize in new carnival, so I suspect they're made by someone else. I've seen them sell for as little as $21 and as much as $56, with the average being about $35.
