One idea could be getting him a deluxe edition of Shakespeare's works, complete with annotations and commentary from notable scholars.
Another idea could be to get him tickets to a local production of one of Shakespeare's plays. Alternatively, you could plan a surprise trip to see the Shakespeare Globe in London.
If he enjoys reading, you could also get him a novel that explores Shakespearean themes and characters, such as Margaret Atwood's "Hag-Seed" or "The Gap of Time" by Jeanette Winterson – modern retellings of "The Tempest" and "The Winter's Tale" respectively.
A more personalized gift could be to commission a custom piece of artwork inspired by his favorite Shakespearean play or character.
Or you can get him a star map with the date when he was born.
