This matchbook must be from the 20’s or 30’s, the heyday of the New Jersey Athletic Club; after that it was a hotel, the club went kaput because of changing demographics. I wonder if some of their 3000 plus members got a workout on these stairs.
It had about 300 basic rental rooms, back then the toilet and showers were probably down the hall. People weren’t so particular.

Now it is the site of the impressive New Jersey Performing Arts Center. I think the members would approve.
