Yes, a book can be a great gift for a 47th wedding anniversary. While there is no traditional or modern gift associated with this anniversary year, a book can be a thoughtful and meaningful gift that reflects your partner's interests and personality.
Consider choosing a book that holds special significance for your relationship or that your partner has expressed interest in reading. You could also opt for a personalized book that includes your own story, such as a scrapbook or photo album of your shared memories over the years.
If your partner is an avid reader, you could also consider gifting them a subscription to a book club or a bookstore gift card so they can choose their own books to enjoy. Whatever book you choose, it's a thoughtful and personal way to celebrate your 47th anniversary and show your love and appreciation for your partner.
