Mr. BELIN - Did you notice what clothes the man was wearing as he came up to you?
Mr. BAKER - At that particular time I was looking at his face, and it seemed to me like he had a light brown jacket on and maybe some kind of white-looking shirt.
Anyway, as I noticed him walking away from me, it was kind of dim in there that particular day, and it was hanging out to his side.
Mr. BELIN - Handing you what has been marked as Commission Exhibit 150, would this appear to be anything that you have ever seen before?
Mr. BAKER - Yes, sir; I believe that is the shirt that he had on when he came. I wouldn't be sure of that. It seemed to me like that other shirt was a little bit darker than that whenever I saw him in the homicide office there.
Mr. BELIN - What about when you saw him in the School Book Depository Building, does this look familiar as anything he was wearing, if you know?
Mr. BAKER - I couldn't say whether that was--it seemed to me it was a light-colored brown but I couldn't say it was that or not.
Mr. DULLES - Lighter brown did you say, I am just asking what you said. I couldn't quite hear.
Mr. BAKER - Yes, sir; all I can remember it was in my recollection of it it was a light brown jacket.
In March 1964, Officer Marrion L. Baker, who had encountered Oswald on the 2nd floor of the Texas School Book Depository, testified before the Warren Commission that Oswald was wearing a light brown garment. The individual depicted in the above image, taken soon after this encounter, is wearing light-coloured attire, but it is too light to be light brown.
So, for the sake of argument, let's assume that the individual in the first image is Oswald, who had removed his upper garment to reveal a light-coloured garment. The evidence indicates that Oswald was wearing a white crew-neck (without a collar) tee shirt, and the person depicted in the photo appears to be wearing a light-coloured shirt with a collar high up on the nape of his neck.
All of this confirms that it is not Oswald in the first photo above.
