The banner in the photograph stands at the entrance of the Matisse museum in Le Cateau-Cambrésis. The caption indicates that the quotation is an extract from a message sent by Matisse to his birth town in November 1952.
«Révéler un peu de la fraîche beauté du monde.»
Which reads in English:
« Revealing a little of the fresh beauty of the world. »
This quotation is a perfect illustration of what Matisse intended with his work. He was aiming for a pure and peaceful sensation.
