In two collected volumes, the creative team behind DC's Batman Li'l Gotham created the perfect all-ages comic. Each issue contained two separate stories about all the happenings in Gotham and most notably, the Bat family.
With its distinct illustrations and welcoming storytelling, Batman Li'l Gotham always felt like it could have been something more in the DC universe. It'd have decent potential as a children's cartoon (maybe even more so than Teen Titans Go!). While that probably won't happen, DC did at least move into collectible figures.
The books are worth the read, and after you enjoy those, you'll be wanting your favorite character sitting on your desk.
