This vase is 6" x 4". My first thought when I saw it was Narumi Fantasy Glass by Sanyu, but then doubt started to set in. Skrdlovice and Aseda (and others?) also made pieces like this one. My mentor for this type of glass agrees on the Sanyu identification, but guessing I may get some push back on my identification if I put it on my glass collection web site. Any thoughts on this one?
