Worth a Quick Look
The museum is worth seeing, along with the plaza next to it. You'll see pictures of this building on most postcards and souvenirs in Leipzig, so it's worth taking a quick walk around it and snapping a few good photos.
Inside the building, there is an old bookstore and another shop that sells old printed pictures, paintings, or designs of German cities, landscapes, animals, or plants. They cost around 10 Euros. I suggest you don't miss this shop; they can be a great souvenir, or even a nice picture you can frame and hang on your wall. It might be the best souvenir you can buy from Leipzig.
