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

Since the gap is just a little too wide to capture the lightpost and the sign in one view, the solution is to use something as a marker to bridge the gap. So, in the top image, you can clearly see the green lightpost on the left, and on the right side, we'll use the woman in the red and blue plaid shirt as the marker. Then, I just progress the film slightly until the sign appears. And wahlee, that clinches it, showing the span between the lightpost and the sign in the Zapruder film, using that woman as the link.

This is a very big deal. If Zapruder captured the sign when he shot the top of the plaza, then he had to capture everything betwen the sign and the top of the plaza. And that means there should be two lightposts.
