~ O lieb' so lang du lieben kannst ~
This stein would make a good Valentine's Day present and the verse is certainly good advice. The stein is marked Dümler & Breiden 891, ca. early 1900's Jugendstil (youth style, modern art) period. This verse was the beginning of a long and apparently popular poem by Ferdinand Freiligrath, a 19th-century German writer. In 1847, Hungarian composer Franz Liszt set the poem to music, and eventually adapted it into his famous Liebesträume (Dreams of Love) No. 3.
 
O lieb' so lang du lieben kannst O love as long as you can love
