~ Wie die Raupe vom Schmetterling ~
This cute monkey dressed in a soldier's uniform with a "Pickelhaube" (spiked helmet) presented as a character stein is a modern copy of an earlier pre-WWII version. It is marked "837 Western Germany" and therefore post-WWII. The verse uses the German symbolism of a "Kater" (tomcat = hangover) and an "Affe" (monkey = drunkenness).
Wie die Raupe vom Schmetterling
stammt vom Affen der Kater.
As a caterpillar comes from the butterfly,
so does the tomcat (hangover) come from the monkey (drunkenness).
