Enjoy this collection of more than 300 vintage hand-tinted and black and white postcards from the 1900s to the 1960s, many dating to the 1940s, when a visiting author declared Pittsburgh America's Gibraltar. Take a nostalgic tour in imagery and text of the city on the three rivers back when it was famous for its steel production and was known by all as the Steel City. Admire its skyscrapers, churches, the arcade building, Union Station, and Mercy Hospital. Meander along downtown's busy Fifth Avenue and climb the mountains Pittsburgh is nestled amongst on the city's astonishing cliff-climbing public transports known as the inclines. Finally, idle away a relaxing afternoon at Forbes Field, Pitt Stadium, Highland Park, the zoo, Nixon Theatre, or bathing at Lake Elizabeth.
