Jumbo's Hide, Elvis's Ride, and the Tooth of Buddha 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). 

Jumbo's Hide is the recent sequel to Lucy's Bones, Sacred Stones, and Einstein's Brain, and it follows the same format. The mummies it describes are:

• Galileo's middle finger ("This is the finger with which the illustrious hand covered the heavens and indicated their immense space. It pointed to new stars with the marvelous instrument, made of glass, and revealed them to the senses. And thus it was able to reach what Titans could never attain" Tommaso Perelli, 18th Century Italian astronomer. It was cut from Galileo's corpse in 1737 and is exhibited in Florence, Italy.
• John Adams's pigtail (Not the president, but the last mutineer of the H.M.S. Bounty to survive on Pitcairn Island.)
• Jumbo the Elephant (P. T. Barnum's famous elephant, which managed to earn some money after Jumbo's demise when he was stuffed and exhibited.) 
• The hoof of Fire Horse Number Twelve (Exactly what it says: the horse was racing to a fire in 1890 in Washington, D.C. when the fire engine was hit by another; the horse's hoof was severed, yet it managed to keep its pace for a half mile to the fire. It is exhibited at the National Museum of American History in Washington, D.C.
• Able the Space Monkey (One of two rhesus monkeys first sent into space on May 28, 1959, Able was later preserved. He is now exhibited at the National Air and Space Museum in Washington, D.C.)

The book contains 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.
