Yup, a genuine, all cotton (maybe some cotton) Cos Cob baseball cap. I bought one, naturally, both to show my regional pride and to allow me to pass as a native during my brief forays into the dark side of town. I could just blacken my teeth and stop bathing and achieve the same effect, but one can carry authenticity just a bit too far, at times.
If they had my sense of humor, which is to say no humor at all, the folks at the Greenwich Reform Synagogue would buy boxloads of these and wear them to the next P&Z hearing. Such fun!
