One idea could be to get your grandpa a complete collection of Kafka's works in a beautiful hardcover edition. This will allow him to revisit his favorite works and discover new ones.
Another idea could be to get him a book on Kafka's life or an analysis of his writing. This could give your grandpa new insights into Kafka's worldview and writing style, which he may find interesting.
If your grandpa enjoys art, you could also consider getting him a piece of Franz Kafka-inspired artwork, such as a painting, print or sculpture. This could be a wonderful addition to his home and a reminder of his favorite author.
Lastly, if your grandpa is a coffee or tea drinker, you could get him a mug or teapot with a quote or image of Kafka on it. This could be a fun and practical way for your grandpa to express his admiration for the author.
Or you can get him a star map with an important date you share.
