How about a beautiful Polynesian-inspired wooden tiki statue or carving? This could be a great statement piece that your grandpa could display in his home or garden. Another idea could be a book filled with beautiful imagery and stories about Polynesian culture, such as "The Art of Maori Carving" by Sid Marsh, or "Polynesian Tattoos" by Tricia Allen. You could also consider a traditional Hawaiian shirt or a Polynesian-style pendant necklace. These gifts could celebrate your grandpa's interest in Polynesian culture, and be a thoughtful and personal Christmas present.
Or you can get him a star map with an important date you share.
