I purchased this at an antique shop some time ago. It is a lamp shade, also known as a denkyu or densan. The green and blue colors are very cute. There is some dirt on the cut edges. Please check the images. This is a sale of the shade only. #Densan #Lamp #Taisho #TaishoRoman #MilkGlass #Antique #OldGlass #ShowaRetro #Industrial #OldFolkHouse #NoRemake
