The Treaty Tree at Shackamaxon fell in a great storm in 1810. Members of the Penn Society, fearing that the story of the Treaty of Friendship between William Penn and the original stewards of the land might be forgotten, placed an obelisk on the site of the Great Elm as a reminder of the simple act of friendship and trust.  The monument is inscribed:

Treaty ground of William Penn, and the Indian Nations, 1682,

Unbroken faith (north face)

William Penn, Born 1644, Died 1713 (south face)

Pennsylvania, Founded, 1681, by Deeds of Peace (east face)

Placed by the Penn Society, A.D. 1827, to mark the site of the Great Elm Tree (west face)

The Victorian trade card (above) is an example of an early form of advertising popular in the late 1800s. The obelisk figures prominently as a Philadelphia landmark and as a symbol of fairness and trust for a local business.
