Excellent condition. this wall sconce is equipped with two light sockets (e14). A professional electrician has checked and prepared the piece to operate in us, uk and eu. this fixture is composed by one smoke glass murano, metal structure and brass screw. this company was founded in vienna by julius august kalmar in 1881. By 1931, kalmar was concerned solely with designing and manufacturing high quality lamps and fixtures in cooperation with the architects of the austrian werkbund, an association of artists, craftsmen, architects and manufacturers founded in 1912. Their purpose was the promotion of a high regard for material, form and function in the hand crafted as well as industrial production of fine art and applied arts. They sought modernity by combining classical tradition and contemporary innovation. Recognized as a typically viennese style by the 1930s, this “moderate modernity” integrated the ornament-stripped purism of adolf loos with more traditional elements.
