How about a signed photo or poster by Jason Momoa? You could also consider getting him tickets to a Comic-Con or a movie premiere that he is attending. If he enjoys reading, you could get him a book or graphic novel written by Jason Momoa. Another idea could be to create a custom t-shirt or hoodie with a design of his favorite character that Jason Momoa has played. Finally, if he's into skincare, you could get him a gift set from Momoa's own skincare line, "ManoFace".
Or you can get him a star map with the date of your anniversary.
