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

I just confirmed with Larry Rivera that this frame does not occur in the Darnell film.

This situation is worse than for the Lovelady "Gorilla Man" clip because even though it doesn't occur within an intact film, we do see it as a clip in some compilations. We see it moving. But, we don't have the above frame in any active form. It doesn't exist as a film- as far as we know. 

Until someone comes up with an intact film which includes this frame, it is on the suspect list for being a complete and utter fraud.
