It’s one of life’s bigger issues – with so many bad guys roaming the streets, skies, sewers and whatever else of Gotham City, how do you keep up with all of them? Thanks to this handy wall chart, you now can.

No excuses for not knowing your Catwoman from your Tiger Bishop or your Lady Clay from your Lady Shiva. You will now not only know all the bad people who call Gotham City home (don’t go there, just by the way, it’s full of them) but you will also be able to see what kind of villain there are in the species sense. From birds to plants and everything in between. They are also broken down by the style of villain they are.

The handy poster comes from Pop Chart Lab and is just US$22 for an 18-inch by 24-inch chart. Each print is signed and numbered by the artists, from a first edition of 500. With The Dark Knight Returns about to hit screens, there’s been no better time for a history lesson.

Price: US$22
