One idea could be to find a rare vintage piece that he might enjoy, such as a leather jacket or an old-fashioned vest. Alternatively, you could look into getting him a subscription to a vintage men's fashion magazine or a book on the history of men's fashion through the years. For a more personalized touch, you could also consider finding fabrics and sewing something yourself, like a shirt or pocket square, using vintage-style prints or colors that would catch his eye. Finally, consider taking your grandpa to a local vintage clothing store to pick out something he likes and make it a fun outing for the two of you.
Or you can get him a star map with the date when he was born.
