On the occasion of their 50th anniversary of service, a medal was donated to the jurist Georg Ludwig Böhmer (1715-1797) and the teacher of constitutional law Johann Stephan Pütter (1725-1807). On the double portrait of the medal, it shows the relationship between conformity and individuality, typical for the representation of professors in the 18th century. Both of them are shown turned to the left in the profile, the neckline and head posture are the same. And although both exhibit individual traits, the uniform depiction identifies them to be part of a larger community of professors.
