These "Streetwise" cards are really perfect, laminated, with the general points of interest. I now use for a long time (Madrid, Barcelona), and it's always handy! I could compare this one with the card Flexi Berlitz Guide to New York as saying that it is -to my view- much better to use a card only: it has no frills, it is quite flat, so convenient to take! A marker can also be used to point to what you want to see, this removes the solvent without damaging the map In addition, they are regularly updated (but not every year), and the one I received is "revised in 2012" (Amazon has always sent the latest maps).
In short: I am very satisfied and I can only recommend these cards, especially at this price !!
