How about getting your dad a copy of the Les Misérables book? If he already has it, you could consider getting him a special edition or a book with illustrations. Alternatively, you could get him tickets to see the musical if it's going to be in your area soon. You could also consider purchasing him a CD or a vinyl record of the Les Misérables soundtrack so he can enjoy the music whenever he likes. Another idea could be a Les Misérables t-shirt, poster or other merchandise.
Or you can get him a star map with the date when he was born.
