I began collecting Blenko glass shortly before I bought Ms. Pina's book earlier this year. I refer to it often when I am searching internet auctions. Initially it helped me determine whether a price was in line with the fair market value. Lately I have been using it to determine to my own satisfaction whether an unmarked piece truely is Blenko. The pictures are very good quality. The only drawback to the book is that is it woefully short on text. It would have been beneficial if the book contained some in depth discussion of Blenko craftmanship and how to distinguish their products from the other WV glassmakers, especially since they all had a tendancy to copy one another.
