~ Gelegenheit zur Rache ~
This pressed glass stein dates to ca. last quarter of the 19th century judging from the handle attachment starting at the bottom, the hinge and the 0,5 L (0.5 L) capacity mark. The capacity marks in the metric system on steins started to be used about 1872. The humorous scene shows a customer at a tavern taking revenge on the tavern owner/waiter that must have done something to upset him. He appears to be getting revenge by tweeking his hair to try to get him to spill some of the beer he's serving.
 
Gelegenheit zur Rache Opportunity for revenge
