As a result, an international clientele has de- veloped whose loyalty and trust is based on expertise and attentive service. Our buyers include private collectors as well as libraries, museums and academic in- stitutions that regularly acquire import- ant works through our auctions. The quality of the department is reflect- ed in both the selection of objects and the thorough cataloguing and provenance research. Each con- signment is examined with the greatest care, de- scribed in detail and placed in its historical context. Our auctions reflect the full breadth of the written and printed word across the centuries: from early incunabula and richly illuminated manuscripts to major Enlightenment prints, literary first editions, modern artists’ books and autographs by outstand- ing figures from culture, science and politics.
