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

So, look at the area of the shirt with the exposed button on Lovelady. Supposedly, it's the same shirt and the same button on the left. But, we're not seeing the button, and we're also not seeing the plaid pattern surrounding the button. 

It's not just the white button that is white on Lovelady. There are also white stripes on his shirt, and they are just as white as the button. But if you look at that upper left corner of Doorman's shirt (that's our left) it is devoid of any of that whiteness. Not the white button and not the white lines. All of it got missed by Altgens' camera, supposedly.

Yet, that same camera supposedly picked up the white on white junction of a white collar overlying a white shirt.

I think somebody gave it some help.
