1930s Hanging lamp from the Netherlands

A beautiful, elegant hanging lamp manufactured in the netherlands (in the style of giso) around 1970. The piece has a grey metal arm and beautiful ball shaped shade. Half of the round shade is made of white milk glass, the other half of very blurred frosted glass. This creates a unique style with the two halves contrasting each other. When lit, it emits a nice warm light that is differently diffused on each half. This makes it very appealing! It remains in good vintage condition with minor wear consistent with age and use, preserving a beautiful patina.
