One Thousand Beards: A Cultural History... by Alan Peterkin is a whole mishmash of a book - With wit and insight, One Thousand Beards explores the historical meaning of beards, mustaches, sideburns, and other forms of facial hair, from Freud's psychoanalytic interpretation, to a wild trip through history, to a rogue's gallery of famous bearded or mustached men, including Abraham Lincoln, Joseph Stalin, Backstreet Boy A.J. McLean, and Yosemite Sam.
