Next to Palacio del Ayuntamiento, in Central Park, we found the small but interesting Museum of Old Liro. After paying a modest entrance fee we could see printed and bound copies of books from the colonial era, including a replica of the first printing press in Guatemala, which was cerca 1660. A pretty, scarcely traveled place, but very interesting, especially if you're a book lover. As I am, I thoroughly enjoyed my time there. The museum's staff (like almost all Guatemalans) were very nice and polite.
