Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

I flooded this image with light. Robin Unger claims that the mean who is seated, wearing a white shirt and tie and also glasses was Otis Williams and that he was the figure we call Obfuscated Man.

It is a reasonable speculation based on the shirt and tie. But, since we can't see the face of Obfuscated Man, it is impossible to tell for sure. 

I always thought Ob Man was Joe Molina, which his testimony backs up.

Mr. BALL. Where were you standing?
Mr. MOLINA. Right at the front door; right at the front door.
Mr. BALL. Outside the front door?
Mr. MOLINA. Yes, outside the front door I was standing; the door was right behind me.
Mr. BALL. Were you standing on the steps?
Mr. MOLINA. Yes, on the uppermost step.

Doesn't it seem like Ob Man is on the uppermost step, one down from Doorman? And Joe Molina, like Otis Williams, fit the bill: short, portly, and wearing a shirt and tie. 

So, this is a tough call.
