A Memorabilia
Make a photo collage of snapshots. It will contain all the events stretching his life in succession. To work out this birthday gift idea, you have to collect the pictures right from his birth. Then dad as a college grad, on job, and finally marriage. The final page will contain snaps of your dad of the day just before he hits 80. The old images will make him laugh. Embellish the album creatively and then gift him.
