The transformation of five traffic signal control boxes or “invisible canvases” around the Northeast Corridor is intended to promote pride and unite the community in the area. These boxes are collectively called The Big Picture Project, a public art initiative that uses the gateways of the community to share the stories of the neighborhood.

In the early 20th century, the Roberts Dairy Company was the most prominent among the dairy farms in the Village of Millersville. To commemorate Roberts Dairy, this traffic signal box has a collage of images of dairy milk bottles and the Roberts family home on three panels.
