One idea could be to get your grandson a vinyl record of John Coltrane's "Blue Train" album, as it's considered one of his best works. Another idea could be a poster of John Coltrane that he can hang in his room. If he plays an instrument, you could also consider getting him a book on jazz improvisation or sheet music for John Coltrane songs. Finally, you could plan a visit to a nearby jazz club or festival to experience live jazz music together.
Or you can get him a star map with the date when he was born.
