NADAZ ART GLASS-PLEASE HELP

I HAVE BEEN UNABLE TO LOCATE ANY INFO RELATING TO THE  VASE PICTURED BELOW.  I WON THIS UNIQUE ITEM AT FUND RAISING EVENT FOR A CHILDRENS AIDS CLINIC IN 1999.  IT HAS BEEN DISPLAYED IN OUR HOME EVER SINCE, BUT MUST THIN OUT SOME ITEMS DUE TO AN UPCOMING MOVE. 

IT IS APPROX. 9" TALL,  5" WIDTH AT TOP, 3 1/2" AT BASE. WEIGHT IS APPROX 3LBS (+/-).  THE TWO  ORIGINAL STORE TAGS ARE VISIBLE ON THE BOTTOM.  "NADAZ ART GLASS"  AND THE BARCODE WITH PRICE TAG OF $375.  I'VE TRIED TO CAPTURE IN THE PICS,  "COPYWRITED NADAZ 95" THAT IS ALSO ETCHED ON THE BOTTOM. 

GRANTED, I'M NOT VERSED ON WHERE TO FIND THIS ITEM.  ANY INFO WOULD GREATLY APPRECIATED.

THANKS,
