A great birthday gift idea for your dad who loves jigsaw puzzles could be a custom photo puzzle. You could select an image that has special meaning to him, such as a family photo or a picture of a place he loves, and have it turned into a jigsaw puzzle.
Another option could be to give him a puzzle subscription box, such as Puzzle Master or Puzzle Warehouse, which sends a new puzzle to his doorstep every month. This would allow him to try out different types of puzzles and keep his mind active.
Lastly, you could consider giving him a puzzle mat and storage system. This would help him keep his puzzles organized and stored neatly when he's not working on them, and it would make it easy for him to pick up where he left off.
Or you can get him a star map with the date when he was born.
