Cooking advertising brand "Kinderpaar", made by "Sigmund Spear, Kunstanstalt Nürnberg."
The picture motif is one of the most original among the advertising brands. It is important to note the text line "KOCH Harmonikas gehen nicht so schnell caput." ("KOCH harmonicas are not going to break that fast."), which makes it very clear what has happened here:
The girl cries out of sorrow over the broken harmonica (which is an inferior product of a competitor), the boy in the then typical sailor suit comforts with a KOCH harmonica.
