Please keep in mind, these images are vintage advertising dated from early in this century...fortunately, much has since changed.
The following would never appear today and even at the time may be considered by some as offensive.
an attractive agricultural scene - Memphis c1917
Not only the graphic depictions are questionable but also what the heck were the contents of this product that supposedly would preserve meats and food stuffs?
Quite a stretch for a medical/pharmaceutical company to use this depiction.
I have many more examples, the times sure have changed but I am sure you get the idea of this presentation.
