Dries "is constantly seeking, he's never satisfied, he's always evolving."J.J. Herbert, in Le Lion (official publication of Lions International) n°28 March 1957, p.12 "I'm working on a big painting that I call Concert Champêtre... I'm sending it to the Tuileries, but I'm not very satisfied with it."Blue notebook, p.31 This dissatisfaction explains why many of his paintings weren't signed. He only signed paintings he was going to exhibit or sell. To his way of thinking, a painting was never completed and he could always alter it. Dries didn't hesitate to destroy paintings he wasn't satisfied with. In 1956 he estimated that he had “done about 1100 paintings including 300 or so which had been destroyed by the artist.”In Les cahiers d'art-documents, documentation put together by Jean Albert Cartier, p. 10.
