My wife and I be visiting Paris in early April and want to buy a guide book for the Louvre before we leave. We aren't looking for an art book as we know pretty much what we want to see (Greek, Roman, Egyptian, Babylonian antiquities and some of the "famous paintings").
It'd be nice if it was small enough to bring into the Louvre, but that's not absolutely necessary as its main function would be pre-trip planning. Maps would be nice, though I suspect we can find some good maps online. It'd also be nice, but not mandatory, if the guide could serve as a souvenir of the trip as well--so something with pictures of at least some of the major pieces.
Mucho grassyass in advance for your help!
