Leading up to the assassination four eye-witnesses saw a slender, white male on the 6th floor of the TSBD building.
They were surely talking about the same man.
“To my best description, a man in his early thirties, fair complexion, slender but neat, neat slender, possibly 5-foot 10… “
[Warren Commission testimony of Howard Brennan]
“Uh---he had a slender face and neck---uh---and he had a light complexion----he was a white man.”
[Warren Commission testimony of Ronald Fischer]
"He was rather slender in proportion to his size...He appeared to be fair complexioned, not fair, but light complexioned, but dark hair…I would say either a light Latin or a Caucasian."
[Warren Commission testimony of Arnold Rowland]
"White man...about average. Possibly thin."
[Warren Commission testimony of Robert Edwards]Obviously, the Nutters want this man to be Oswald and believe that the description - white, slender male - fits Oswald so perfectly that it couldn't apply to anyone else (

)
However, once we begin to examine their descriptions of this man more closely it starts to become clear that the man they are talking about is not Oswald at all.
CLOTHES"Light colored clothes, more of a khaki color…not a real white shirt, in other words. If it was a white shirt, it was on the dingy side.”
[WC - Howard Brennan]
“...he had on an open-neck shirt…It was light in color; probably white..."
[WC - Ronald Fischer]
"He had on a light shirt, a very light-colored shirt, white or a light blue or a color such as that. This was open at the collar. I think it was unbuttoned about halfway, and then he had a regular T-shirt, a polo shirt under this, at least this is what it appeared to be."
[WC - Arnold Rowland]
"Light colored shirt, short sleeve and open neck."
[WC - Bob Edwards]
The collective statements of the four eye-witnesses reveal that the man on the 6th floor was wearing a shirt that was so light coloured it was almost white, best described as an off white colour. The shirt was open at the collar.

This is the shirt Oswald wore to work that day. There is zero chance this shirt can be described as white or almost white (note to Nutters - don't bother with the 'all colours become white in daylight' argument)
HAIR
One of Oswald's most distinguishing features was his receding hairline. Both Fischer and Brennan observed the man on the 6th floor looking towards the direction of the triple underpass meaning Oswald's receding hairline would have been fully on view. It is notable that neither man mentions a receding hairline. Neither does Bob Edwards. And Arnold Rowland makes the following observation -
“It didn't appear as if he had a receding hairline…it was either well-combed or close cut.”It seems unthinkable that Oswald's most prominent feature went unnoticed.
Clearly, the man on the 6th floor didn't have a receding hairline (but he did have a bald spot a few inches above his hairline according to Amos Euins. Another thing Oswald didn't have)
COMPLEXIONThis might seem unusual but it is a detail often overlooked.
Three of the witnesses - Brennan, Fischer and Rowland - describe the man as having a fair/light complexion:
“To my best description, a man in his early thirties, fair complexion, slender but neat, neat slender, possibly 5-foot 10… “
[WC - Brennan]
“Uh---he had a slender face and neck---uh---and he had a light complexion----he was a white man.”
[WC - Fischer]
“Seemed, well, I can't state definitely from my position because it was more or less not fully light or bright in the room. He appeared to be fair complexioned, not fair, but light complexioned, but dark hair.”
[WC - Rowland]Ronald Fischer expands on the importance of this detail:
“Yes; one thing--and that is in the picture he looked like he hadn't shaved in several days at least. And--uh--I don't know whether at that distance, looking at him from the street in the School Book Depository Building--if I could have been able to---if I could have seen that. I think, if he had been unshaven in the window, it would have made his complexion appear--well---rather dark; but I remember his complexion was light; that is, unless he had just a light beard.”Oswald had a dark, unshaven complexion. Fischer had a very good look at the man on the 6th floor but never believed it was Oswald.
