I have every reason to believe that we could be looking at a thirty year old man in this picture. They say that smoking stunts growth, and he could have been smoking since he was a baby. That would account for the small size. Fact is that you just never know with these old pictures. One thing we do know is that everyone was smoking back in the day, so if it was a kid, I wouldn't be surprised.
Seeing old pictures like this, or especially old movies, I really want to smoke a cigarette. It's terribly obvious how much movies influence me. A character I like just need to smoke once and I'll go buy a pack of cigarettes. Fight the urge, folks. It's not worth it. That cool, refreshing smoke isn't worth it.
