ENGLEMANN, Gottfried. - Amateurs executant une courante.

A group of amateur musicians are seen performing/practicing inside a public restroom, using clysters and chamber pots as their musical instruments. A delightful 'toilet humor' lithograph.
"Toilet Humor" is a type of off color humor dealing with defecation, urination, and flatulence, and to a lesser extent vomiting and other bodily functions - popular with a wide range of ages, but especially with children and teenagers.
