A chart of the constellations Pegasus and Equuleus

An illustration of the constellations Pegasus, the winged horse, and Equuleus, a horse said to be either the brother or foal of Pegasus. The outline of the constellations are pricked out and with yellow shaped holes for the stars, so they are illuminated when the card is held up to the light. The stars are shaped to represent their apparent magnitude. From Braun's 'Himmels-Atlas in transparente Karten'.
