Gallery: Historic Keystone Marker Images

We are excited to present a variety of user-submited historical photos incorporating the Keystone Markers. As we receive them, we will include them here. The photographs below illustrate the variety and ubiquity of the Keystone Markers in the early part of the twentieth century on Pennsylvania highways.

Town Name Markers

Waterway Markers

Directional Markers

Traffic and Facility Markers

Large Markers

These large wooden signs in the shape of Keystone Markers were placed all along Pennsylvania’s highways at notable elevations. They are among the most photographed markers historically, as they were convenient for posing next to on long drives. None of these huge markers exist today, so these images are all that is left.
