"24h à Venise pour rencontrer Boulez."Signed autograph postcard addressed to André-Philippe Hersin
"Brother Maurice and brother A. Philippe walk while reading the latest issue of Les Saisons de la Croix...! 24 hours in Venice to meet Boulez. Tomorrow Milan. I think of you very much - M."
Journalist, dance critic and editor-in-chief of Les Saisons de la danse, Hersin was a great defender of Béjart's choreographic style and devoted laudatory articles to him in his review as well as monographic fascicles on his work.
