Hi, and welcome to the GMB.

unusual looking piece, very slightly like a jack-in-the-pulpit vase - hope someone is able to help you, but in the meantime I'd suggest that if possible you also include a picture of the base - this can help sometimes in providing an answer. Compliments on your pictures by the way.
However, it's probably best to stick to the usual form of qualification for 'antique', rather than applying it to items as recent as this.
