Fabulous signed ADNA (Nash) art glass vase. NASH or ADNA glass was produced by Jimmy Stewart who also produced Tiffany's pastel line. This isn't Tiffany glass, but because Jimmy Stewart worked for both Tiffany and Nash, there are virtually no differences in both firms pastel glass beyond the signature. Please refer to the American Art Glass Book, p. 59 for more information. Doug Nash's operation closed in 1931. This vase is pictured in the book with a list price of $900. It measures 4 7/8" tall x 6 3/4" diameter across the top. Perfect condition. No nicks, damage, abrasions of any sort. Any marks you may see in the photo are just light reflections. A stunning vase for any art glass collection.
