How about getting her a rare or special edition comic book that she may not already have in her collection? You can search for rare comics online or visit a local comic book store to see if they have any limited edition ones available. Another option could be to create a custom comic book featuring the two of you as the main characters. You can hire an artist or use an online service like Artifact Uprising to create a personalized comic book that she will treasure. Finally, you could consider getting her a subscription to a comic book newsletter or magazine, so she can stay up-to-date with the latest releases and news in the comic book world.
Or you can get her a star map with the date of your first kiss.
