The Sargent Welch Scientific Company of Skokie, Illinois has been producing (for a very long time) those great old science charts that many of you may remember from the school rooms of your past.

This Guinea Pig (captioned in Latin) comes from a strikingly beautiful black & white chart entitled "Genetics," which documents all of the things that can happen re the offspring when a "Rough Black" Guinea Pig does what comes naturally with a "Smooth White."
