Miss Essie Dellering lived in Hellam, a township in eastern York County, PA.

This area, on the western bank of the Susquehanna River, was the site of the Codorus Forge and Furnace in the Colonial Era.

In the early 19th century, Hellam Township included stations on the Underground Railroad.

Sometime around 1915 (this postcard was not mailed and lacks features which would help us determine a date), Essie was given a postcard greeting by Esther Keller.

The face of the postcard bears an illustration of a girl standing beside a large wall-mounted tablet.

The girl, in a white dress with a banded pattern, is turning a new page on the tablet.

The tablet is framed by a border of four-leaf clovers and clover blossoms; at the girl’s feet is a bouquet of flowers.

Although there is no printed greeting, I believe that this is a postcard for the celebration of the New Year.

In a quick internet search, I could not find either Esther Keller or Essie Dellering.

One hopes that Essie and Esther remained friends and correspondents and that they had many “new beginnings” in the early 20th century.
