This is a valuable antique lamp by the Müller Frères, renowned as a masterpiece of interior lighting decoration from the Art Nouveau and Art Deco periods. The Müller brothers, originally from the Moselle region on the French-German border, honed their glassmaking skills under Gallé after evacuating during the Franco-Prussian War. They became masters of Art Nouveau glass, and this piece, made with vitrification-colored glass, was carefully crafted by them from around the 1910s to the 1920s. Acid signature present. The shade glass, with its beautiful vitrification colors of pale green, blue, brown, and yellow, is stunning. Furthermore, this Müller shade is unusually made of uranium glass. This is a very rare piece. (Shade angle can be adjusted) The light bulb has been replaced with an E17 25W bulb. Size: Approximately 57cm in height, base 18cm x 18cm Feel free to comment.
