Hi and welcome to Sactownpickers!
I am a purveyor of unique and eclectic vintage home decor.

Fun and unique Frankoma beer mug / stein!

Made for Schmidt Beer and The Heidelberg
A wagon & wheel on one side with The Heidelbery
name beneath
The opposite side is the name Schmidt and its slogan

in German:

"The brewery that grew with the great Northwest"

My guess is, this was made for a restaurant or bar

called The Heidelberg in the 1960s, there are many!
