I received this photos a while ago from Hans Schmitt. This is from his email: "There used to be a resort on the property where Eilenberger's Landing Lane leaves River Road and heads down to a bennikill of the Delaware River behind the Shawnee Golf Course island. The Riverside House was owned by August Kron, who was Caroline Schmitt's uncle. Attached is a copy of the brochure, unfortunately, the only copy we had is stained."
The other photos, according to Hans is August Kron and a woman who is probably his wife.
