My Dad loved to take photos. I believe this photo of the Salt and Pepper Shaker (Rolo Plane) is was from the late 1940's or early 1950's. Front of Marine Pier looking towards the Playland Carousel building. That Rolo Plane graced the pier until the late 1960's.
Good question. This was before my time but I have seen those cabins in other photos of the pier. Restrooms maybe? Convenient to put them in the middle of the pier if that's what they are.😁
