A woman dressed in a lab coat is facing the reader, and is holding sheets of white paper. She is pointing towards something on the paper and appears to be mid-sentence.

The visual depiction of a scientist serves as a visual symbol of scientific and technical expertise. I was slightly surprised by the ad including a woman because the majority of ads from this time period have used men as symbols of industrialization. 

The ad highlights personalized service and problem-solving, rather than the sulfur compounds themselves. This reinforces the claim that customers receive more than just chemical ingredients.

The paper folder evokes ideas of laboratory data, specifications, or formulation plans, symbolizing the collaboration between manufacturers and suppliers.
