For your wife's anniversary gift, you could consider creating a customized scrapbook or photo album filled with blank postcards for her to collect from places you travel or visit together in the future. You can also include some of her favorite postcards that you've already collected, and let her know you're always thinking of her and her interests. Another idea is to get her a subscription to a postcard club that sends out monthly postcards from various parts of the world, or purchase a vintage postcard from her favorite place and frame it as a special keepsake for her.
Or you can get her a star map with the date of your anniversary.
