Mars 2018, Yves Vasseur, former Secretary General of Mons 2015, Europe's Capital of Culture, has a well-deserved rest. Always passionate about Vincent Van Gogh's work, he has just bought the book Van Gogh's capital by Wouter Van Der Veen, published by Actes Sud. "In the middle of the book there was a small illustrated notebook with only two famous photographs of the artist, 13 years in 1866 and 19 years in 1873, he recalls. Until then I had always seen the 13-year-old in square format, zoomed on the face. " That day, for the first time, he discovers the complete picture.
