Our book Graphic Design: The New Basics by Ellen Lupton and Jennifer Cole Phillips talk about how scale is relative and a motion, among the others as well. I feel this comic from

Action Comics No. 1 June 1938, Superman!

Superman, found in Action Comics No. 1 June 1938, utilizes these two ideas well.

 
Let us start with motion. Looking at the placement of the car we can infer its moving. In fact, our eyes might just move between the top three photos rather quickly, due to the lack of words. But this allows us to see the scale in which superman is exerting his strength of the massive car and moving it in the photos. It helps we are familiar with the build of man and typical size of cars, making it easier for the reader to interpret the story.

In the second frame the car looks relatively larger because the cropping of this does not let us see the whole far but frames most of it. Leading us to think it is closer to us and larger. This can also be said for when we compare the car to Superman himself, he is a slightly above average male size, and the car is much larger than himself. We are also left guessing in the bottom right frame, where the barn is very small and Superman and Butch and “normal” sized as they climb up the power line pole.
