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

Do you see these black and white lines that Upperpunk showcases, indicating a match between Doorman's shirt and the plaid posing shirt of Lovelady? 

Impressive, isn't it? Except that it's all drawn in.

And look how Lance deliberately worked with a dark image, even though on the day in question, Doorman was standing in the bright sunlight. 

Doorman's shirt isn't plaid. It isn't checkered. Try playing Checkers on it. It's a tiny image that was blown way up, producing distortion. Plaid means boxes:horizontal and vertical lines crossing and forming boxes. See if you can find a single box on Doorman's shirt.

And the white streaks are light reflections; they are too wide to be lines. The white lines on Doorman's shirt were pinstripes.

In sum: the variation and contrast we see on Doorman's shirt was due to haze, distortion, and light reflections. And, the fact is that Oswald's shirt did have a fine grainy pattern. 

Lovelady's posing shirt could not have been the shirt worn by Gorilla Man because his had a pocket with a big pocket flap which Lovelady's posing shirt didn't have.

You see that big ol' pocket flap on the left? It's missing in the center and on the right.

Even the cuffs were different.

Nothing works about this claim. 

1. Doorman's shirt was not plaid. It was just grainy, but also thin and worn and shiny in spots, which reflected light. 
2. Lovelady's shirt was not plaid. He didn't wear a plaid shirt. He wore a striped one.  And it was short-sleeved. 
3. The plaid shirt seen on Gorilla Lovelady is obviously not the same plaid shirt that Lovelady posed in- unless you think the pocket flap ripped off. 
4. It's odd that the shirt still fit him snugly considering that he lost a lot of weight after the assassination. You know, stress, from having to lie about being Doorman; it hurt his appetite. 

So, nothing works. It's just a big fat lie by the bloodied. Doorman was Oswald.
