How about "True Detective" merchandise or a DVD set of the show? Here are some other ideas:
1. A True Detective themed t-shirt or hoodie.
2. The novel "The King in Yellow" by Robert Chambers, which is often referenced in the show.
3. A subscription to HBO so he can watch the show and other HBO originals anytime he wants.
4. A True Detective themed poster or piece of artwork.
5. A gift certificate to a local brewery or whiskey distillery, to bring him into the dark, moody world of the show.
6. A book of noir short stories or a David Lynch film to really lean into the show's style and aesthetic.
7. A True Detective themed board game, an idea that's perfect for quality time spent with friends.
8. An experience visiting prominent locations used in the show. This experience can include a tour through places like the Mount Washington Hotel in Bretton Woods, New Hampshire where the show was shot.
9. An opportunity for him to attend a True Detective cast Q&A session, meet and greet portions or signings, or other events.
10. A pocket knife or multi-tool, just like the one used by Rust in the series.
Or you can get him a star map with the date when he was born.
