Tiffany Favrile, Blue Decorated Bowl
You probably know that blue Tiffany Favrile glass is rarer and more desirable than gold Tiffany Favrile glass. Decorated (in this case with green leaves & vines) blue glass is the next step up.
This little double-lobed bowl, 2¾" tall x 4½" diameter, is as good as this shape gets. The color and iridescence are superb with strong blue on the exterior and purple on the interior. The form is elegant. The brass flower frog is original and almost always lost. It's a miracle this one survived 100 years.
The condition is mint, with an original very minor flaw on the underside rim (visible in the third photo). It's iridized, original to the day it was made, and only mentioned for accuracy.
