How about getting him a coffee table book related to one of his interests? For example, if he's into photography, you could get him "National Geographic: The Photographs," or if he's into art, you could get him "The Art Book" by Phaidon. Another great option would be "Humans of New York," a book about the stories of the people who live in New York City. This would allow him to learn more about the city he loves while enjoying a coffee table book.
Or you can get him a star map with the date when he was born.
