How about a Peaky Blinders-themed gift basket? You could include a DVD or Blu-ray box set of the show, a Peaky Blinders hat, a bottle of whiskey or scotch (since the characters in the show enjoy drinking), and maybe even a copy of the book "Gangsters and Goodfellas: The Rise and Fall of Henry Hill" by Nicholas Pileggi, which inspired the show. You could also add in some snacks or treats that your grandpa enjoys, like his favorite candy or cookies. This way, you're not only giving him something related to his interest in the show, but also something personalized and thoughtful.
Or you can get him a star map with the date when he was born.
