Hello there, I have this amazing readers digest antique spot globe. It is in good, working condition save for some age related wear. The globe has a bulb inside, which illuminates through the worlds wind patterns and contour shelves in the ocean. The globe has dials at its base that allow the user to control the exact position of the inner light where the user has to set the lattitude and the longitude but the longitude knob is broken but you can still tune it using the small white inner knob (See pictures). With regards to visible wear, i have repleced the top knob with a wooden dowel but the wheel can spin easily. The lamp is perfect for academia or school use, and its vintage style adds a touch of nostalgia to any room. From the ground up, the globe has a height of 40cm.
