A great anniversary gift idea for your boyfriend who loves Kurt Vonnegut would be to get him a special edition of his favorite Kurt Vonnegut book. You could also consider getting him a complete collection of Kurt Vonnegut's work as a special and thoughtful gift. If your boyfriend likes to wear accessories, you could get him a Vonnegut-inspired scarf, handkerchief or a tote bag with his favorite Vonnegut quote. Additionally, you could plan a surprise date to see a play based on one of Vonnegut's books, or a movie adaptation.
Or you can get him a star map with the date of your anniversary.
