Thomas Webb Ribbonette Pattern Decanter

This is a Thomas Webb "Ribbonette" decanter. Webb's pattern number 33130, made 1910-28. It has a molded zig zag pattern running up the body.

This is lovely tall and sinuous decanter in the Art Noveau style. I think it is quite rare as my reference books only have pictures from adverts and not the actual decanter. I know they made it in amethyst, and I would love to get one of those...... sigh.
