~ Wer öfters seinen Rucksack packt ~
This modern stein seems to be an advertisement for the health benefits of hiking with a backpack loaded with the essentials, ca. post WW II.
Wer öfters seinen Rucksack packt, den packt gewiß kein Herz-Infarkt!	Whoever often packs his Rucksack, certainly does not pack a heart attack!
