Square glass lampshade, white in colour, dating from the 70s. If you are a little bit handy yourself, you can make a very beautiful and unique hanging lamp. Buy some lamp wire, fittings and some loose parts and make your own lamp. You can tie a bunch of caps together, or position them at different heights, or like a spiral staircase. Well, you can go truly creative!
Lampshade shows normal traces of use.
