This is a glazed and etched Mettlach stein mold number 2075 designed by Otto
Hupp and dated 1892. In the Mettlach catalog it is listed as "Sinnbilder der
Eisenbahn" (emblems of the railroad), but often errantly called the "Telegrapher"
stein. The telegraph is represented on the stein, but was only part of the overall
railroad system which was government run as shown by the Imperial Eagle on the front
and the thumblift. The verse on the lid is my personal favorite and the cognate
word "chug" has all the same multiple meanings in German and English and has a
double meaning here. Note
that the steam locomotive is being fueled by Hofbräu beer contained in the
stein sitting humorously on the tender car.
