Boston Public Library's Flickr Photostream - A Blast from the Past

Want a blast from the past? The Boston Public Library has uploaded thousands of old photos and postcards to its Flickr photostream with albums featuring:

• Accidents: Aviation
• Accidents: Miscellaneous
• Accidents: Train & Trolley
• Aerial Photographs
• Animals: Farm & Domestic
• Aviation: Charles Lindbergh
• Alabama Postcards
• Alaska Postcards
• Arizona Postcards
• Arkansas Postcards

Those are just some of the interesting albums I found before getting to the albums starting with "b." Have fun killing an afternoon perusing the seemingly endless supply of interesting images.
