Kosta Unik Vase 1973 Ann Warff?

Description

Up for bid is a Kosta Unik Vase made in 1973. Not sure of the artist and I can not identify the signature .Looks to be work of Ann Warff. The vase stands 5" tall and measures 4 1/2" across the mouth. The design is very textured and most of the blue glass can be felt on the inside of the vase. Besides being signed on the bottom, there is an inscription on the side toward the bottom saying "BLA-BLAD 11 . What I can figure out on the bottom is : Kosta Unik 1973 233BTo Glenda? Love, then signed maybe Ann? Researching I came up with nothing. If you have any information on this piece, I would like to hear from you. Thank you for taking a look.
