Lucy's Bones, Sacred Stones, and Einstein's Brain by Harvey Rachlin is filled with fascinating stories about historical objects and artifacts. Of course, history being the strange thing that it is...some of these stories pertain to mummies, since people have been preserving all types of unusual things as mementos (including themselves). 

The books contain some photos, but the key here is the background information on each of the preserved objects or beings. Rachlin is an excellent author and researcher; the other chapters (though not about mummies) are equally fascinating.  Highly recommended. 

In Lucy's Bones, a number of mummies are discussed in separate, well-researched chapters, including:

• John Paul Jones, often referred to as the Father of the American Navy (complete with photos of his mummy), 
• philosopher Jeremy Bentham, (he wanted to be a mummy, and he got his wish)
• Stonewall Jackson's Horse (more of a taxidermist's project than a mummy, Little Sorrel is exhibited at the Virginia Military Institute), 
• Einstein's brain, (approximately 200 pieces of the brain exist in various locations around the world, including Lawrence, Kansas, U C at Berkeley, and Japan, Australia, and Germany

Another chapter tackles the contents of King Tut's tomb. But the strangest mummy-related chapter is the one that deals with Napoleon's mummified member (allegedly removed the day after he died, though there is no proof that this happened) and now residing at the College of Physicians and Surgeons at Columbia University (New York). 

Jumbo's Hide, Elvis's Ride, and the Tooth of Buddha is the recent sequel to Lucy, and it follows the same format. 

Highly recommended.
