~ Nun so wollen wir noch einmal ~
This is a Mettlach stein #1526/3592 dated 1899 with a hand painted scene and vagabond type song. The word "Heirassassa" has no meaning. It is just used to help carry the tune, such as "fa,la,la,la," is used in a well known Christmas carol.
 
Nun so wollen wir noch einmal
lustig sein fröhlich sein Heirassassa!
Now here we go again
to be joyful and merry Heirassassa!
