A stunning, large Art Deco glass bowl in deep amethyst, circa 1925, strongly attributed to the master designer Andries Dirk Copier for Glasfabriek Leerdam. This impressive, thick-walled vessel showcases the elegant, minimalist style of the period, designed as a floating flower vase—simply add water and let blossoms drift beautifully on the surface. It is a powerful statement piece perfect for any collector of Dutch Modernism.
