One idea for a Father's Day gift for your grandpa who likes Oprah Winfrey could be a subscription to Oprah's magazine, "O, The Oprah Magazine." Another option could be a book by Oprah herself such as "The Wisdom of Sundays: Life-Changing Insights from Super Soul Conversations" or "What I Know For Sure." You could also consider a personalized message from Oprah, which you can purchase through the website Cameo.
Or you can get him a star map with an important date you share.
