Pinnochio (Disney) Easter Egg - Hidden Mickey

After Gepetto comes downstairs and discovers Pinocchio, there is a pan shot where Gepetto passes a chair whose back is shaped like the distinct Mickey Mouse silhouette. My wife says it is a coincidence, but I disagree, especially after surfing to this site. I think it's a hidden Mickey. It seems like an awfully unlikely shape to make a chair, if you ask me.

I do have one doubt, however: the silhouette shape looks like the logo Disney uses today. Back when Pinocchio was released, was Disney using this logo? Had they even thought of it yet? What do you think?
