One idea could be to get her a personalized comic book of your relationship. There are websites that offer services where you can upload photos of the two of you and have them incorporated into a custom comic book. Another idea could be to get her a rare or limited edition comic book that she has been searching for to add to her collection. You could also consider tickets to a comic book convention or signing event with one of her favorite artists or writers. Finally, if she loves to read, you could get her a subscription to a monthly comic book box service so she can discover new titles and authors.
Or you can get her a star map with the date of your anniversary.
