Image description

Lines Appearing not Parallel. In this striking illusion the two vertical red lines appear curved, although they are perfectly straight and parallel to one another. This effect is caused by the surrounding dark brown lines converging towards the centre. Illustration for one of a set of cigarette cards on the subject of Optical Illusions, published by Ogden's, early 20th century.
