The organic, curvilinear designs of Art Nouveau influenced painting, architecture, and sculpture but made their most lasting impression on the decorative arts. This volume combines two rare and important early 20th-century portfolios to present nearly 200 full-color stained glass designs. Featuring chiefly the works of Arnold Lyongr?n, the book also includes authentic, royalty-free designs by Raoul Bacard, Ren? Beauclair, Rudolf Geyling, and other masters.
