This vintage white hobnail milk glass electric lamp is a beautiful addition to any collection. The ornate key switch adds a unique touch to this mid-1900s piece. The glass material and white color make it a timeless piece that will complement any home decor. Measuring 5.5 inches in diameter and 4.5 inches in height, this lamp base has a vintage feel that is perfect for collectors. The glass is in great condition but the metal does show some wear. The lamp does work- turning it on requires a half turn of the key and turning it until it clicks turns it off. I don't know if this is the original way it was designed or if there's a short.
