Block and Daisy Vase, Imperial

Not often seen. These 5 1/4 inch tall vases appear to have been made from a lamp shade mold but I can find no evidence that they were ever made as such. This one is pink and is marked LIG. Made between 1978 and 1982. Also known in ice blue (Horizon Blue), made 1979-1980. Either color would be valued at between $15 and $25.
