One idea could be to find an antique or vintage item that is related to a hobby or interest he has (such as a vintage camera, tool, or instrument). Another idea is to give him a book or guide about antique collecting, or take him to a museum exhibit or auction for antique items. Additionally, you could consider giving him a personalized antique or vintage item, such as a pocket watch or monogrammed cufflinks, that he can appreciate and pass down to future generations.
Or you can get him a star map with the date when he was born.
