How about a custom-made Pop Art portrait of your dad? You can find many websites that offer this service, where you upload a photo of your dad and they turn it into a Pop Art masterpiece. You can choose from different styles and colors, and they can even print it on canvas or have it framed for you. Another option could be to get him a Pop Art coffee table book, featuring famous Pop Art works along with the history behind the movement. Lastly, if your dad enjoys DIY projects, you could buy him a Pop Art paint-by-numbers kit, which provides all the supplies needed to create his own Pop Art piece.
Or you can get him a star map with the date when he welcomed you in this world.
