One idea could be to get him a book of plays written by his favorite playwright. You could also purchase tickets to see a play or a theater performance in your area. Another option could be to give him a personalized notebook or journal where he can jot down ideas for his own plays. Additionally, you could get him a membership or a subscription to a playwriting workshop or class, or offer to take him to one as an anniversary experience.
Or you can get him a star map with the date of your anniversary.
