You might not believe it but I bought one of these in 1987 and I'm still using it! (and a DC one the following year, still have that). I keep it in my car and have GPS in-car plus iphone now, but I used it a lot before GPS was invented and still pull it out once in a while to see what bridge is nearer if I'm in Brooklyn as I do not have a good sense of direction and my GPS always wants to send me via the midtown tunnel or the battery tunnel and make me pay a toll. NYC has changed, obviously, but the point is, this really lasts well if you treat it nicely and has everything you need for Manhattan at a glance. I would note that the new ones I've seen in stores look like they are made with the same great quality material. Other maps I've had from other companies that are more expensive are literally falling apart with less use after a year. It's not quite as convenient as those origami maps that fold up business card size, but it's much more durable as those wear out after a few months. Streetwise rocks!
