John Bennett (also spelt 'Bennet') was royal instrument maker to the Dukes of Gloucester and Cumberland. By the 1780s, his busines, based at the Globe at Crown Court, between St Ann's Soho and Golden Square, had been taken over by his apprentice James Search. The card advertises optical and philosophical instruments: those which are represented include telescopes, spectacles, sun dials, quandrants, a globe and an orrery, and a demonstration device to show the motions of the Earth and Moon around the Sun - popular during the 17th century.
