Topic: Assistance Please with Paperweight Artist Identification

[Bill Vitez]

 Hi, could someone please assist with an identification of a signed paperweight? It stands about 5.5  inches tall by 2.3 inches at its widest point and is an elongated 4-sided pyramid atop another inverted 4-sided pyramid. There is a number "WOAR0087" etched on the bottom and a signature near the base on one side dated 1990 that is unintelligible. The style with the black swirl line is very reminiscent of a Hal David Berger piece that I own but his signature on that piece appears on the bottom and is quite legible. A great find no matter what but I'm curious to know who the artist may be.
Thank you for any assistance!
Bill
