One idea could be to get your grandpa a book of poetry written by a poet he admires or a collection of poetry from various poets who have participated in poetry slams. You could also look for tickets to a poetry slam event in his town or a nearby city that he would enjoy attending. Another thought might be to create a personalized poetry slam for him by writing and performing a poem or song that reflects his life or experiences. Finally, you could consider purchasing some fun poetry slam swag, such as a t-shirt with a favorite poem or a hat from a slam event he's attended in the past.
Or you can get him a star map with an important date you share.
