about picture of aunt em and Dorothy

Rating: 10/10 (2 July 2014)

I have noticed at the beginning of TWO oz Professor Marvel does this crystal ball thing with Dorothy and he takes her basket and pulls out a picture of Dorothy and Aunt Em. After he looks at it he stuffs it under his leg and does not give it back to Dorothy. I wonder if anyone knows about this and what the purpose of it might be. After watching the movie several hundred times since I was about 7 years old in the 50's,this is the first time I noticed it, about a week ago. I have noticed things like this in other movies that I have seen many many times and just when I thought I learned the entire dialog and every movement in this movie, I see something new that I have never seen before. Thank technology for VHS or a lot of things would go unnoticed and anyone watching a certain movie would not get the full benefit of the director's effort. If anyone can respond please do.
