How about getting her a vinyl record of The Who's greatest hits or one of their most famous albums like "Tommy" or "Who's Next"? You could also get her a t-shirt with The Who's logo or a poster to hang on her wall. Another idea is to buy her tickets to see The Who in concert if they are performing near your area or a concert DVD of one of their shows. If she's into reading, you could also get her a biography of the band or a book about the making of one of their albums.
Or you can get her a star map with an important date you share.
