Question: Where is it rumored that Andy Warhol bought a mummified human foot from Ancient Egypt?
About the article "Andy Warhol", section "Collections".

Candidate passages:
Warhol was an avid collector.
His friends referred to his numerous collections, which filled not only his four-story townhouse, but also a nearby storage unit, as "Andy's Stuff."
The true extent of his collections was not discovered until after his death, when the Andy Warhol Museum in Pittsburgh took in 641 boxes of his "Stuff.
"Warhol's collections included airplane menus, unpaid invoices, pizza dough, pornographic pulp novels, newspapers, stamps, supermarket flyers, and cookie jars, among other eccentricities.
One of his main collections was his wigs.
Warhol owned over forty and felt very protective of his hairpieces which were sewn by a New York wig-maker from hair imported from Italy.
In 1985 a girl snatched Warhol's wig off his head.
It was later discovered in Warhol's diary entry for that day that he wrote "I don't know what held me back from pushing her over the balcony.
"Another item found in Warhol's boxes at the museum in Pittsburgh was a mummified human foot from Ancient Egypt.
The curator of anthropology at Carnegie Museum of Natural History felt that Warhol most likely found it at a flea market.
 studies on human remains.
Due to the considerable anthropological, archaeological, and public interest directed toward human remains, it is only natural that they have received a similar amount of attention from the DNA community.
Due to their obvious signs of morphological preservation, many studies utilised mummified tissue as a source of ancient human DNA.
Examples include both naturally preserved specimens, for example, those preserved in ice, such as the Ötzi the Iceman (Handt "et al."
1994), or through rapid desiccation, such as high-altitude mummies from Andes (c.f.
Pääbo 1986; Montiel "et al."
2001) as well as various sources of artificially preserved tissue (such as the chemically treated mummies of ancient Egypt).
However, mummified remains are a limited resource, and the majority of human aDNA studies have focused on extracting DNA from two sources that are much more common in the archaeological record – bone and teeth.
Recently, several other sources have also yielded DNA, including paleofaeces (Poinar "et al."
2001) and hair (Baker "et al."
2001, Gilbert "et al."
2004).
Contamination remains a major problem when working on ancient human material. 
The people of Ancient Egypt worshiped Sobek, a crocodile-god associated with fertility, protection, and the power of the pharaoh.
They had an ambivalent relationship with Sobek, as they did (and do) with "C. suchus"; sometimes they hunted crocodiles and reviled Sobek, and sometimes they saw him as a protector and source of pharonic power.
"C. suchus" was known to be more docile than the Nile crocodile and was chosen by the Ancient Egyptians for spiritual rites, including mummification.
A recent DNA test found that all sampled mummified crocodiles from "Grottes de Thebes", "Grottes de Samoun", and "Haute Egypt" belonged to this species.
Sobek was depicted as a crocodile, as a mummified crocodile, or as a man with the head of a crocodile.
The center of his worship was in the Middle Kingdom city of Arsinoe in the Faiyum Oasis (now Al Fayyum), known as "Crocodilopolis" by the Greeks.
Another major temple to Sobek is in Kom-Ombo; other temples were scattered across the country.
Historically, "C. suchus" inhabited the Nile River in Lower Egypt along with the Nile crocodile.
Herodotus wrote that the Ancient Egyptian priests were selective when picking crocodiles.
Priests were aware of the difference between the two species, "C. suchus" being smaller and more docile, making it easier to catch and tame.
Herodotus also indicated that some Egyptians kept crocodiles as pampered pets.
In Sobek's temple in Arsinoe, a crocodile was kept in the pool of the temple, where it was fed, covered with jewelry, and worshipped.
When the crocodiles died, they were embalmed, mummified, placed in sarcophagi, and then buried in a sacred tomb.
Many mummified "C. suchus" specimens and even crocodile eggs have been found in Egyptian tombs.
Spells were used to appease crocodiles in Ancient Egypt, and even in modern times Nubian fishermen stuff and mount crocodiles over their doorsteps to ward against evil. 
Warhol-o-rama is a book of American poetry that examines the life—and robust afterlife—of the artist Andy Warhol (1928–1987).
A poetic sequence by Peter Oresick, it employs techniques of multiple perspective and Warholian parody and appropriation, often to humorous effect.
The sequence draws heavily from source material in the archives of the Andy Warhol Museum as well as a large body of mythology surrounding the pop art icon to render a postmodern serial portrait of Warhol.
The book was published on 6 August 2008, the occasion of Andy Warhol's 80th birthday, by the university press at Carnegie Mellon University, of which Warhol was an alumnus.  
Pruitt and Jonathan Horowitz collaborated on an installation piece called Peacock Hill.
In 2003 they bought a ramshackle, eleven-bedroom Victorian mansion in Fleischmanns, New York, painted it black, and decorated it like a haunted house with faux taxidermy and gothic furniture.
Outside they arranged a graveyard using plywood tombstones with sardonic inscriptions.
Ken Johnson compared it to the self-mocking art-as-life collaborations of Gilbert and George but overall described the project as self-congratulatory.
Pruitt used tombstones again in a 2008 show where he created monuments for celebrities who had died the previous year.
They were installed in a room whose walls were papered in a year's worth of iPhone photographs.
In 2011 Pruitt created "The Andy Monument" for the Public Art Fund; it is a ten-foot-tall, chrome-finished statue of Andy Warhol.
The sculpture resided outside the building that housed Warhol's Factory in the 1970s and early 1980s.
