Pennsylvania Keystone Markers … Symbols of our Past and Bright Future

Nathaniel Guest & Greg Prichard, Historic Preservationists

October 16, 2013 @ 7:00 pm 9:00 pm

$15 / person

The Keystone Marker Trust was founded in 2010 to protect the historic keystone-shaped town marker signs of Pennsylvania. These signs, typically painted blue and yellow, are found throughout the Commonwealth and were installed starting in the mid-1920s by the Pennsylvania Department of Highways, the predecessor to PennDOT. Though many towns have adopted and cared for their markers, there was no central group to advocate for them until the formation of the Trust. In addition to documenting and restoring historic markers, the Trust has also begun making new Keystone Markers for the first time in about 70 years, which are accurate in appearance to the originals.

Founding members of the Trust, Nathaniel Guest and Greg Prichard will speak about the history of Keystone Markers, their meaning, an overview of Keystone Markers found on the Main Line, the work of the Trust, and the process by which new reproduction markers are created.
