Vintage Unique Hand Thrown Studio Pottery Goblet 8" Tall 1970's signed stamped W

This unique ceramic pottery goblet was acquired by my husband in 1972 at the Coconut Grove Art festival in  Miami, FL, it measures 8" tall and has a raised initial in the front "W" in a circle, was not able to find another like this one, it has a unique decoration where the vessel meets the stem, looks like Art Nouveau designs scrolls. the stem is brown and the cup is green the cup has a shiny glaze and the stem is  more matte. Lovely piece.
