An amazing science poster! This vintage science poster has great graphics and features all you need to know about "Mechanisms of Correlation". Learn about the Nervous System, Reflex Actions, the Brain, Learning and Forgetting, Fatigue and info about Sleep. Published in 1946, it measures 42" inches by 28.5" inches wide.

Because of its age it shows some water damage (warping) on the left side of the poster. It would look great in a custom frame.
