One idea could be a book about Barack Obama's life and presidency, such as "Becoming" by Michelle Obama or "Dreams from My Father" by Barack Obama. You could also consider getting her a framed photo of the two of them, or a documentary about his life and political career. Another idea could be tickets to see Barack Obama speak at a future event if he has any scheduled appearances near your area.
Or you can get her a star map with the date of your anniversary.
