~ Kraft und Muth gibt stärke ~
This is a self evident verse on a blue/gray, salt-glazed, stoneware stein marked with the Reinhold/Merkelbach logo and mold # 8, ca. 1900. The "power and strength" in this case appear to come from the beer in the stein being drunk with breakfast (not recommended).
Kraft und Muth gibt stärke
zum neuem Tagewerke.
Power and spirit give strength
to a new day's work.
