Jean Ranc, an eminent French portrait painter, was sometimes annoyed by impertinent and vexatious criticism. Having exhausted all his talent upon a particular portrait, the friends of the sitter refused to be pleased, although the sitter himself appears to have been well satisfied. In concert with the latter, Ranc concerted a plan for a practical retort. After privately painting a copy of the picture, he cut the head out of the canvas, and placed it in such a position that the original could supply the opening with his own veritable face, undetected.
