How about getting your husband tickets to a Comic Con event that he has been wanting to attend? It could be a fun experience for both of you to share, and he will be able to enjoy all of the exhibits and events that the convention has to offer. Another great idea could be getting him some exciting merchandise from his favorite comic book series or fandom, such as a graphic novel or a prop replica. You could also consider creating a personalized comic strip featuring the two of you in the style of his favorite comic series. This would be a unique and fun way to show him that you understand his interests and want to share in them with him.
Or you can get him a star map with an important date you share.
