These Murano lamps were produced by Vetri Murano and can be hung on the wall or can be used as table lamps as well. They also come with a cable and switch to be used freely in the room or can also come without so they can wired to the wall directly. The lampshades are all slightly different due to the glass nature. 
The bases are made of white enamel. Four screws hold the lampshade in place. 
The bases come with slight wear such as chips and dark spots consistend with age. I will gladly send more pictures before I ship out. 
The lamps all come with original stickers from the maker. 
Overall in great vintage condition. 
Currently 5 pieces available.
