How about gifting him a first-edition copy of one of Toni Morrison's books? This would be especially meaningful if it's a book that he hasn't yet read. You could also consider buying him an autographed copy of one of her works if that's within your budget. Another idea could be to plan a weekend getaway to a place significant to Toni Morrison or where she lived and wrote some of her works. You could also incorporate Toni Morrison quotes or themes into a handmade gift such as a scrapbook or personalized writing journal.
Or you can get him a star map with the date of your anniversary.
