All the other lobby cards are clearly scenes from the film and I don’t see why this one should be any different.

Did somone point a camera at this to take the photo? Yes of course they did.

Did somone point a video camera at this thing of course they did. It is in the film. But we don’t get the much needed close up. It would probably fall as alternate take and be cut in at the storm troopers and escape pod scene for all 2.5 seconds right at the start or something it would be a short shot

It probably won’t be that angle either.

Unless the shot was achieved by walking or dolly past camera movement to make it appear the dewback was moving. A trick basically.

And did the trick work?

A close up shot would have been filmed without doubt. Why bother making this prop so detailed if it was only ever going to appear in distant shots?

The only other mention of a shot that could be missing is smoke rising from behind the sand dunes as an establishing shot for the destroyed sandcrawler.
