The auto was in its infancy, and sheep still grazed along South Broad Street. But there was a vibrancy in the air as the 20th century began, the pulse of a great city rising to meet the industrial challenges of the new age. The optimism all but jumps off the pages at you in this marvelous collection of historic photographs of Philadelphia, assembled by the Philadelphia Inquirer. They span 100 years-from Republicans gathered in Philadelphia in 1900 to nominate William McKinley for president to planning for a GOP convention in 2000; from boys registering for the draft in World War I to boys resisting the draft for Vietnam. From Connie Mack's Athletics to Mike Schmidt and Pete Rose; from such Philadelphia icons as Kate Smith, Marian Anderson, and Paul Robeson to Grace Kelly, Bill Cosby, and Sly Stallone. They're all here-an unforgettable experience and a "must have" for people with roots in the Philadelphia region.
