Hi guys... I need help!!

This is going to sound so vague... A long long long time a go, I saw a beautiful painting of a father with his little girl. My father and I have a beautiful relationship, we both appreciate art, and I want to get him something very special for christmas. Even a print of a famous painting would be fine - I just want something he could hang in his office. Do you have any suggestions? For the life of me I can not find the painting nor remember who painted it. I thought perhaps if people gave me ideas, I could find it that way, or maybe even another one that would do. Thanks so much!!
