A lovely anniversary gift idea for your girlfriend who likes collecting postcards could be a personalized postcard album or a wooden postcard holder. You could also consider gifting her a unique postcard collection from a destination that you both love and could plan a trip to together in the future. Another idea could be to order custom postcards with your favorite memories and moments of your relationship and have them delivered to her periodically throughout the year. This will not only add to her collection but also be a thoughtful way to reminisce on your time together.
Or you can get her a star map with the date of your anniversary.
