A few years ago, one of our designers at work did a design which had a photo from a very early auto race depicted within a border that had 35mm sprocket holes. I laughed at their ignorance and told them there was no way that image would have been taken on 35mm film. It was so obvious since the amount of ovaling present on the wheels would have at least required a 4x5 with focal plane shutter.

They didn't seem to understand.
