A crossword puzzle book can be a great gift for your grandpa. Or you can make it even more special and personal by creating a crossword puzzle with clues and answers related to your grandpa's life, hobbies, and interests. You can also consider gifting him a crossword-themed coffee mug or a personalized crossword-themed T-shirt. Another idea could be a subscription to a crossword puzzle magazine or an app that offers daily crossword puzzles.
Or you can get him a star map with an important date you share.
