As a pair of hands put cans of soup into a wood crate with the Campbell brand stamped on it, you can clearly see a pull tab on top of one of the two first cans. At this time, soldering the cans closed was the only method used. The labels indicate the soups before the redesign of the label to red and white.
The soup can being packed in the wooden box is an aluminum pull top can that was not invented until 1997 and Campbell's did not introduce them until 2000. In 1895 cans were made of tin and were opened with shears or knives.
