One idea could be getting him a Vinyl record of one of Madonna's classic albums such as "Like a Prayer" or "True Blue". Or, you could get him a concert DVD or Blu-ray of one of Madonna's live performances that he may not have seen before. Another option could be purchasing official merchandise from Madonna's website such as a t-shirt, poster, or mug that he can proudly display. Finally, you could consider getting him a book about Madonna's life and career such as "Madonna: An Intimate Biography" by J. Randy Taraborrelli or "Madonna: Like an Icon" by Lucy O'Brien.
Or you can get him a star map with an important date you share.
