One idea could be to get him a beautiful leather-bound journal for him to write his poetry in. You could personalize it by having his name or a special quote inscribed on the cover. Another option could be to gift him a book of poetry by one of his favorite poets or a collection of famous poems. Additionally, you could consider signing him up for a poetry workshop or class in his area so he can continue to grow his skills as a poet.
Or you can get him a star map with an important date you share.
