For digital and print editions of Vincent van Gogh: The Letters: The Complete Illustrated and Annotated Edition (Vol. 1-6). This has made the letters accessible to both a specialist readership of art historians and literary scholars and also to lovers of van Gogh, who at last have the opportunity to read the letters as they were written and in their proper art historical context. The correspondence was published in an edition of 10,000 in Dutch, French and English, and has been distributed worldwide. An exhibition at the van Gogh Museum was dedicated to this event.
