My son isn't interested in picture books. He only likes books with photographs, specifically of cats and dogs. We tried pigs, but the only page he liked was the one that also had a dog on it. I guess he can't make the connection between the icon and the animal yet. I'm a very creative person, but I'd argue that maybe I'm not a very imaginative one. Obviously I love drawings and pictures, but as a kid I had no interest in dinosaurs, because, like my child and the board books, they just didn't seem real enough. I've never had an interest in celebrities, since I'll never meet them and thus they might as well be fiction. Heck, I make a webcomic and I choose to create one that's 85% non-fiction! So, I guess maybe this is where my kid gets it.
