Your typical “greetings from” postcard shows a generic illustration of fields, a country road, a lake, or whatever. This one, at least, does appear to have been taken in Pequannock. It shows a lovely view of the river… with Newark’s four-foot water pipeline crossing it.
An idyllic scene, ostensibly from Pompton Plains. It’s probably a generic card, as witness the blocky font with the town’s name. “Greetings from YOUR TOWN HERE”.
