How about the DC Comics Encyclopedia? It's a comprehensive guide to all the characters, locations, and stories in the DC Universe. Another great gift would be a set of graphic novels of his favorite characters or storylines such as Batman: Year One, The Killing Joke, or Watchmen. If your husband is into collectibles, you could also consider getting him a limited edition action figure, poster, or statue of his favorite DC Comics character. Finally, if he is a coffee or tea drinker, you could get him a DC Comics-themed mug or tumbler.
Or you can get him a star map with the date of your first kiss.
