Very rare astronomical broadside. The engraving shows the comet and an egg which was presumably laid by a hen before the comet appeared, depicting the comet’s declination. The copper engraving of different version shows, in addition, the hen and bears two lines of text. VD17 lists only 1 copy of the other version in Munich.
