How about purchasing tickets for a ballet performance? You could plan a date night and make it extra special by getting dressed up and having a fancy dinner beforehand. Another idea could be to purchase a ballet book or DVD collection so your husband can learn more about the history and techniques of ballet. If your husband enjoys playing music, you could also consider purchasing a ballet-themed sheet music or CD.
Or you can get him a star map with the date of your anniversary.
