How about getting him some books by Franz Kafka that he hasn't read yet? You could also consider getting him a special edition or a set of books that includes all of Kafka's major works. Another idea is to gift him a Kafka-inspired piece of art such as a print or painting. If he already has a lot of Kafka books, you could consider getting him something related to Kafka's life, such as a biography, or a book on Kafka's style of writing. Alternatively, you could get him tickets to see a play or movie based on Kafka's works, or even take him on a trip to Prague, where Kafka lived and set many of his stories.
Or you can get him a star map with an important date you share.
