How about a special edition of one of Kurt Vonnegut's books? You could get him a signed copy or a first edition copy of his favorite Vonnegut novel. Another idea would be to gift him a collection of Vonnegut's lesser-known works or short stories. You could also get him a Vonnegut-inspired T-shirt or mug, or tickets to a film screening or play based on one of Vonnegut's works. Lastly, consider making a gourmet meal at home filled with dishes inspired by Vonnegut's work, or planning a visit to a literary festival or downtown literary tour dedicated to Vonnegut's life and work.
Or you can get him a star map with the date of your first kiss.
