That my friends is RARE in my book.

Earl C. Slipher (25 March 1883-7 August 1964) was a legendary Planetary Astronomer and a member of the International Astronomical Union, Chairman of the International Mars Commission and Director of the Lowell Observatory in Flagstaff, Arizona.

He is most famous for his book The Photographic Story of Mars which he then followed up with this book published in 1964 by the Lowell Observatory, Flagstaff, Arizona and the National Geographic Society of Washington, D.C.

There are 62 Photographic Plates indeed…

…each plate illustrates one or so cool features of the planets he photographed: Mercury, Venus, Mars, Jupiter and Saturn with explanations of each and every plate.
