One idea could be to make a donation in your grandpa's name to a local community organization that he has shown interest in or volunteered for in the past. You could also consider getting him a membership to a local community center or cultural organization that he would enjoy visiting. Another idea is to create a personalized photo book for him, documenting his involvement and contributions to various community organizations over the years. Additionally, you could purchase a commemorative plaque or plaque for his home acknowledging his contributions to the community.
Or you can get him a star map with an important date you share.
