One of the earliest Blenko pieces in my parents home was the 'hoot owl' ashtray in cobalt. It sit on my father's desk in what is now referred to as a 'man cave'. It stunk to heaven because he didn't clean it out often. He's long gone but I still have the ashtray and happy to report, it wasn't any worse for the wear. I have two 'sisters' for it in other colors. You are right-- those suckers are heavy. You drop one of those on your foot and you'll know it. I love the book ends which have the same owl patter and have them in many colors.
