One way to capture the attention of a boy of any age is to hold a Batman party. Batman may be the most popular comic book character in the world, so it's no surprise that he is a popular party theme choice. A Batman party can include everything from bags and balloons, to costumes and party favours.
Gotham City is everywhere because Batman is everywhere. From video games to movies, his cape casts a massive shadow. Turn on the Bat-signal.
