A book subscription box could be a great gift idea for your dad. You could sign him up for a monthly service that delivers a new book or a curated selection of books based on his reading preferences. You could also consider buying him a book by his favorite author or a collection of books from his favorite genre. Additionally, you could gift him an e-reader if he doesn't already have one, so he can easily access and read his books on-the-go. Another idea is to arrange for a visit to your local library, where you both can spend some quality time together exploring and borrowing books.
Or you can get him a star map with the date when he welcomed you in this world.
