How about a vinyl record of one of The Who's albums, perhaps their iconic album "Who's Next"? You could pair it with a record player if she doesn't already have one, or if she does, consider getting her some speakers or headphones to enhance her listening experience. You could also look into concert tickets if they're on tour, or a poster or artwork featuring the band for her to hang in her space. Finally, consider a book about the band or their history, such as "The Who: The Official History" by Ben Marshall.
Or you can get her a star map with the date when she was born.
