The Keystone State
"Virtue, Liberty, and Independence"
December 12, 1787
Now the official state tartan as decreed in House Resolution No. 548 dated January 26th, 2012, the Pennsylvania tartan was designed by the late Wm.H. Johnston in 1992. It is based on the Black Watch which served at the Battle of Bushy Run, near Pittsburgh, in 1763, thus assuring western Pennsylvania and the "Ohio Country" for Great Britain.
