Cobalt Blue Controlled Bubble Paperweight /Circa 20th Century

I went back to Volunteer's of America to pick this up. I saw it yesterday but put it back after I found the Henry Summa piece. I don't have a cobalt one so this was mostly for the color. It's nice too about the size of a baseball. No signature and a torn label on the small polished bottom. You can only make out some numbers and the word "Blue". Lots of bubbles in the center make it look like stars in the night sky when the light passes through it. Intergalactic ! -Mike-
