Vase / Lamp Shaped / Hobnail Vaseline Opalescent Glass, Imperial Glass USA

Description

At first I thought this may be called a courting lamp or fairy lamp, but it’s all one piece. I think it may be a vase shaped like an hurricane oil lamp. Not exactly sure what it was designed to be?? Has Imperial Glass mark on bottom (see photo). It’s a unique piece and a really pretty piece of collectible glass, and it’s in really great condition, no chips or cracks, very clean.
