How about getting him a special edition of J.D. Salinger's famous novel, "The Catcher in the Rye"? You could also consider getting him some of Salinger's lesser-known works such as "Nine Stories" or "Franny and Zooey." Alternatively, you could purchase a biography or a memoir about Salinger, so he can learn more about the author's life and career. Another idea could be to take him on a literary-themed trip to visit some of the locations that inspired Salinger or to attend a literary festival or event related to Salinger's work.
Or you can get him a star map with the date when he was born.
