Vintage Jon Kuhn Art Glass Paperweight / Vase – Signed. Jon Kuhn SIGNED Glass Paperweight / Vase. Jon Kuhn is regarded as one of the leading glass artists in the world. With works featured in over 30 international museums including the Metropolitan Museum of Art, The Carnegie Museum, White House Permanent Collection, National Museum of American Art and hundreds of private residences and public spaces. 4 inches across widest point. Not 100% sure when this was made, as it is not dated, and there were no comparable pieces upon research. It is possible this is an early work. The only imperfections detected (bubbles inside, lumps/bumps around opening) all appear to be from the hand made glass production processes. The bottom (underside) shows superficial, if any scuffing /shelf wear. Will be packaged with care.
