Collection of Herbert Keuper, Germany Herbert Keuper (海爾伯特∙科爾泊爾) 收藏，德國 no. 編號 1 – 88 Mr. Keuper has been specializing in Chinese art for decades and has built up his private collection of Chinese art in the course of about 20 trips to China between the 1970s and the early 90s. Every piece he acquired was intensively examined for its authenticity, including with the collaboration of Chinese and German experts. Professionally, Mr. Keuper was active as a dealer of antique Chinese art, always made his acquisitions with great care and thus, in all the years, never had a complaint about the identification of an object. He had a comprehensive collection of over 300 specialized books by renowned authors about Chinese antiques (which could also be offered for sale as a whole). This private collection is now being sold due to reasons of age.
