Full of surprising anecdotes, this book tells the story of the discovery in 2018 that one of only two known photographs of Vincent van Gogh (1853-1890) is, in fact, of his brother, Theo. The detective-style narrative continues from there to Samuel Delsaut, who found two drawings attributed to Van Gogh in 1958. The archives of the Delsaut family revealed details casting doubt on the authenticity of these drawings, along with abundant correspondence between Samuel’s son and the son of Dr. Paul Gachet, who cared for Van Gogh in Auvers-sur-Oise. A real-life lesson in historical criticism, this book, beautifully illustrated with reproductions of Van Gogh’s work, has resonance with our contemporary predicament distinguishing information from rumor, journalism from propaganda.
