"In the Manner of Delvaux may seem too slight a work to inaugurate so substantial a reversal in artistic practices and style. After all, the photographic collage did not attract much attention at the time of its creation.  But Duchamp was a magician in the economy of small gestures. One of the delights that drew him to the world of chess was the way in which the simple movement of a pawn by one square could rearrange the dynamics of the entire board. In the Manner of Delvaux was just such a pawn, advanced a single square on the chessboard of his art."
