I purchased this 2 vases a while ago, and been meaning to post them on here to get an idea of who made them. They are both signed. The small vase is signed "gok 1977" I think, and the taller one is signed "PROMETHEUS 78". The later one looks to be American, but have no idea of the smaller piece. It is very thick for its size, and has Pulegoso type bubbles all around, in different sizes.
Any help would be greatly appreciated!
