One idea could be a book called "A Promised Land" by Barack Obama. It is his memoir of his early political career up until his first term in the White House. Another idea could be a coffee mug with a picture of Barack Obama on it and a quote from one of his speeches. Additionally, you could purchase a poster or print of a famous image of Obama, such as the "Hope" poster, to hang in your grandpa's office or home. Finally, you could consider purchasing tickets for your grandpa to attend a lecture or event where Obama is speaking, if he is planning on making any appearances near your area.
Or you can get him a star map with an important date you share.
