I'm not really sure on this one, it has the quality of a piece of Mt. Washington Crown Milano, but the shape is similar to Wave Crest's Helmschmeid swirl design, I'll have to let you Mt. Washington and Wave Crest experts decide on this one. Whoever did it, they made a stunning piece of art glass!
It has ten swirl twisted panels, each one is hand decorated with beautifully detailed blue and lavender Johnny Jump Up flowers.
The biscuit barrel measures ~ 7-1/2" tall x 5-1/2" wide, and is in excellent condition. The silver plated lid is in good antique condition, with general wear commensurate with age.
I've included lots of photos, please take a look and please message me if you have any questions.
