Armstrong County is located in western Pennsylvania, near Pittsburgh. It was carved out in 1800 from sections of Allegheny, Westmoreland and Lycoming Counties and named for John Armstrong, who represented Pennsylvania in the Continental Congress and served as a major general during the Revolutionary War. Most of the postcards shown here are from the county seat of Kittanning, situated along the east bank of the Allegheny River, and meaning “on the main river” in the Delaware language of local peoples.

Hi
You have a picture of the Town Hall and St Laurence Church in Reading on your site. Sorry to disappoint you, but this is Reading Berkshire UK, not Reading PA. The picture was taken by British photographer Francis Frith in 1893.
Thanks, I will remove it!
