One idea could be to get her a vinyl record of one of AC/DC's classic albums, such as "Highway to Hell," "Back in Black," or "Dirty Deeds Done Dirt Cheap." You could also consider getting her tickets to an AC/DC concert if they are on tour, or a concert poster or t-shirt from a previous show. Additionally, you could arrange for an AC/DC tribute band to play at a private event, such as a party or romantic dinner. Another option is to browse Etsy or other online stores for unique AC/DC-themed jewelry or art pieces that she can wear or display at home.
Or you can get her a star map with the date of your anniversary.
