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

Another thing they did was alter the cuff on Oswald's shirt. They expanded it. They made it much wider than it was. It actually was very snug. 

In case you're thinking that Lovelady's cuff was like that, think again. First, he wore a short-sleeved shirt, and he posed in it for the FBI. Here he is doing that alongside how it got captured on 11/22.

So that is Billy Lovelady on February 29, 1964 (left) and on November 22, 1963 (right) wearing the same shirt. 

And even the bogus plaid shirt that he later claimed to wear didn't have a cuff like we see in the Altgens photo.

There is no way those two are the same cuff and the same shirt. Notice the criss-cross pattern on Lovelady's cuff that is absent from Doorman's. Again: there is no way they could be the same shirt. 

So, all this was just a vain attempt to hide Oswald's very distinguishing stance and the exposure of his bracelet.

And actually, even that's not right. To make the image on the left look close to the Before, it would have to be like this, because that guy fused to Doorman wasn't there, and they plopped the top of Lovelady's head on top of Oswald's, from the forehead up.
