Red glass table lamp by Karel Volf, 1970s

This lamp was designed by Karel Volf (it's often misattributed to ŠtěpánTabera, who designed very similar items) in the 1970s and manufactured by OPP Jihlava in the former Czechoslovakia. The inner layer of glass is white, the outer layer is bright red, and when illuminated it's a beautiful deep shade of orange. 
It is in very good condition. The wiring is original and fully functional.
