A great gift for your grandpa who likes The Crown could be a hardcover coffee table book titled "The Crown: The Official Companion, Volume 1: Elizabeth II, Winston Churchill, and the Making of a Young Queen" by Robert Lacey. The book offers a behind-the-scenes look at the acclaimed series and features exclusive interviews, photos, and stories about the characters and historical events portrayed in the show. Another option could be to purchase a DVD or Blu-ray set of The Crown's first season or second season, so he can enjoy watching the show whenever he wants. Alternatively, you could also purchase a royal-themed gift such as a set of Crown-themed whiskey glasses or a fancy tea and crumpet set to go with his daily dose of the show.
Or you can get him a star map with the date when he was born.
