As one would probably predict based on the name of the place, the Picasso Museum has nothing but Picasso paintings. Make sure you set aside a few hours to accomodate this event. Waiting in line is at least a good half hour or so, and tourists should watch out for pickpockets. There is a gift shop that sells images of Picassos works as postcards, as well as many other souveneir items. There are many side shops that sell the same thing, and sometimes they are cheaper.
