Au dos : "Fores's Optical Illusions, published at 41, Piccadilly. Screw on one subject at a time, - hold it before a Looking Glass, looking through the small holes, - the distance regulated by the eye. Turn round the subject some one way and some the other. Care should be taken to have a good light upon the subject. They show well by candle light. Fores has just invented a Machine called an Exhibitor, by which two persons may view at once two subjects, without a looking glass, the objects appearing more clear and distinct. The public are respectfully cautioned against some greatly inferior subjects, with a similar title, as also a clumsy and ill-adapted imitation of his Exhibitor, so peculiarly suited to his superior Illusions"
