As well as the relics of the Cretaceous and other prehistoric periods, Lanzendorf collects the treasures of Asia. Over the course of decades, he filled his Chicago Gold Coast home with rare Indian miniature paintings, centuries old Chinese porcelain, Ming Dynasty bronzes, Khmer and Rattanakosin period Buddhas, along with rarities from India, Thailand, and Burma.
For Lanzendorf, ancient art and artifacts should be displayed to promote a harmonious symphony. At auctions, private sales, and in the ancient places themselves, Lanzendorf added to his collection objets d’art, monumental furniture, temple and shrine devotional items, paintings and sculptures—each of them offering a glimpse of the diversity of cultures and genres to which he is drawn.
