Print of the constellation of Cassiopeia

One of a set of thirty-two cards designed by 'a young Lady,' to make the study of astronomy 'familiar and amusing'. It shows Cassiopeia as visible in the night skies of Britain, with an easily identifiable classical embodiment. The card is pricked through with holes of different sizes so that the amateur astronomer can hold it up to a light and get an immediate impression of the apparent magnitude of each star. Engraved by Sidney Hall.
