We rented the same big house in Rye, NH we all stayed at last time we were up visiting my wife's aunt & fam back in 2018. It's a great house and just a quick walk to the beach.
Seems to be an electrical box painted as a 1966 Topps Tony Conigliaro. Pretty cool tribute to the Massachusetts folk hero. (Found an article on it.)
Ruby was pretty happy to see me after my wife picked her up in the morning. Here she is doing a headstand at my feet to celebrate the homecoming.
