Lewis Davenport had this miniature lens produced showing a publicity postcard drawn in 1930 by George Cooke (who was not the Cooke of Maskelyne and Cooke). The miniature lens fitted into a ring and would have served as a novelty give away. When held very close to the eye, and looking through the lens towards a bright light, the image becomes visible. Details of Stanhope lenses can be found on the web. It is very hard to obtain a photograph of what is seen when you look through the lens. We wish to thank Ken Scott for the very clear image which is illustrated here.
