Signed Iridescent Floral Art Nouveau Hand Painted Lustre Ruffled Glass Shade

Stunning vintage/antique hand-blown art glass lamp shade. Features a breathtaking multi-color iridescent, pearl-like lustre finish that catches the light beautifully. The body is exquisitely hand-painted with detailed pink and purple floral motifs, blue-gray foliage, and delicate gold branch accents. Finished with a classic ruffled, wavy rim. The handpainted florals includes prominent pink purple blooms with soft blue-gray leaves & berries and accented with delicate gold detailing. The edge is distinctly ruffled or wavy reflecting Art Nouveau or Art Deco influences, similar to designs by Tiffany Studios and other art glass producers. The lip that attaches to the lamp measures approximately 1/2 tall. See photos for additional measurements. No damage observed, minor vintage wear. Please review all photos as they are part of the description.  This shade is signed, however I've not been able to confidently identify it yet. It could be Erwin Eisch or Poschinger or someone else entirely, however it does have many characteristics of a German glassmaker.  #ArtGlass #VintageLampShade #IridescentGlass #HandPainted #ArtNouveau #VictorianDecor #Grandmillennial #FentonStyle #LustreGlass #HomeDecor
