Great John Lotton signed art glass vase dating to c1991. Excellent original condition with pink opaline flowers over an iridescent background and the vase also has an amethyst tint. Very nice iridescent vining and the vase is in excellent original condition. Measures 5 1/4" tall and about 4 1/2" diameter. Smartly polished pontil. Reminds me of the multi flora paperweight vases you see.
