It sounds like your friend has a passion for DC Comics, specifically the graphic novel Batman: The Killing Joke. This means that a great wedding gift idea for them would be something related to this comic book. Here are a few ideas:
1. Batman: The Killing Joke (Graphic Novel) - If your friend doesn't already own a copy, consider getting them one. This graphic novel is widely regarded as one of the best Batman stories ever told, and it's a must-have for any fan of the DC Comics universe.
2. Batman T-Shirt - A T-shirt featuring Batman is a perfect way to show off one's love for the character. You can find T-shirts with images of the classic Batman logo, Batman cartoons from the 90s, or, of course, the cover of The Killing Joke.
3. Batman Print - If your friend has a wall in their home or office dedicated to their fandom, consider giving them a Batman art print. There are countless options available online, from minimalist black and white prints to detailed and colorful illustrations.
4. Batman Mug - A mug with a Batman theme is a practical and fun gift. Your friend can enjoy their coffee or tea in the morning while showing off their love for the Dark Knight.
5. Batman Chess Set - If your friend enjoys playing board games, consider getting them a Batman-themed chess set. These sets often feature characters from the Batman universe as the different chess pieces, making for a unique and thoughtful gift.
Ultimately, the best gift for your friend will depend on their specific interests and tastes, so try to think about what else they might enjoy besides Batman. However, if you stick to something related to their favorite comic, you are sure to get a winning gift!
