This is a great mid-century German biology poster, dated 1964. It illustrates the difference between male and female hormone thyroxine and would have been used as a teaching aid in a school or college. The poster is in a good condition for age with light signs of wear and tear that can be seen in the photo's. This is a quirky, interesting piece that is great to add a statement and talking point on display in your home or business.
Measurements: Height of poster 120cm. Width 183cm.
