Beautiful and rare wall sconce in the Amsterdam School style.
To make this lamp requires complicated techniques.
Such as bending the double-layered glass and then firing the colors onto the glass.
De Nieuwe Honsel has the most prominent reputation for producing lights like this.
The firm started circa 1923 and continued with production until 1932.
This lamp was made around 1930 and is the only one known worldwide with this pattern thus far.
The lamp measures 38 cm long.
