Comparative Magnitude of the Planets Greetings Card

Regular price $4.00 Sale

The image on this greetings card depicts the comparative sizes of the known planets within our solar system, and the known satellites including the moon. Two small images at the top show the phases of Saturn (i.e. our changing view of its rings) and the Phases of Venus.

They were created in response to a demand for popular science products within the mid 19th century, and were intended for informal learning within the home. They could be bought in sets or singly and, at a price of 1 shilling, were affordable to middle class audiences.
