How about creating a personalized poetry book or frame that includes his favorite poems, as well as some original pieces written by you? You could also plan a romantic picnic where you both read and exchange your favorite poems while enjoying each other's company. Another idea could be to attend a live poetry reading or open mic night together. Additionally, you could consider purchasing a signed copy of a book by his favorite poet, or writing out a meaningful poem on nice stationary and framing it as a gift.
Or you can get him a star map with the date of your anniversary.
