For your grandpa's birthday, you could consider getting him a unique and rare stamp to add to his collection. Here are a few ideas:
1. A vintage or limited edition stamp from his favorite country or location.
2. A personalized stamp album to help keep his collection organized and protected.
3. A subscription to a stamp magazine or catalog so that he can stay up to date on the latest trends and additions to his hobby.
4. A stamp magnifying glass or a special kit that includes all the necessary tools for stamp collecting such as tweezers, tongs, and a stamp dryer.
5. A framed display of several of his favorite stamps, which he can hang in his home or office to admire.
