~ Das deutsche Lied ist unser Hort ~
This patriotic theme has run in Germania for centuries and was adopted specifically in this form by the Singing Association Kürnberg in Linz, Austria in 1921. The Jugendstil (youth style = modern art) stein is marked with the logo of Steinzeug Industrie and black ink "789", ca. early 1900's.
Das deutsche Lied ist unser Hort,
und unser Spruch,
ein Mann ein Wort.
The German song is our refuge (treasure),
and our motto (is),
one man one word (pledge).
