I date this to very very early 20th century and by Loetz in a Phanomen droplet pattern.....I have seen several vases like this over the years, but never one with the solid color glass body. Excellent original condition and quite large at about 9 3/4" tall and 5 3/8" at widest. A few small air bubbles in the glass from the making. Excellent super striped iridescent droplets leading down the rim and neck as shown. Really a fantastic larger example. Polished pontil as shown.
