How about a book signed by Gabriel García Márquez? Many bookstores offer signed copies of his books, and it would be a great addition to his collection. If that's not possible or exceeds your budget, you could consider getting him a book by another Latin American author that he might enjoy, such as Mario Vargas Llosa or Isabel Allende. There are also beautiful editions of his famous novel "One Hundred Years of Solitude" that make for great collector's items. Another idea could be framed artwork inspired by his books, such as a print of a magical realist painting or a map of Macondo.
Or you can get him a star map with an important date you share.
