Images of the Nazca lines in the book

Mirror of the Gods: Ancient Astronomy and Celestial Navigation was a book on paleoastronomy. Indiana Jones kept a dusty copy of it in his house in Bedford.

In 1957, after translating Harold Oxley's riddle out of Koihoma, Jones pulled out this book from his shelves to show pictures of the Nazca Lines to Mutt Williams. It also held a sketch depicting Akator. Jones tore a few pages out of the book before departing for Nazca with Williams.
