This is an antique color lithograph book plate from a volume of Zeitschrift für populäre Astronomi (Journal of Popular Astronomy), published by Lith Anst, Graz (Austria), c. 1876. The image itself was created by Rudolf Falb (1838-1903), an Austrian popularizer of natural history, who also popularized the concept of extraterrestrial influences on geophysical phenomena!  The eclipsed sun is jet black, with super rich red for the solar flares.

8 7/8"" x 6". Very good condition, with some age toning around the edges and a bit of minor staining. Blank back.
