What is ESGE-Zauberstab? Where does it come from? I found a cup with
measurements on it and that logo. Was it purchased in Los Angeles
where I live?

Dear Just Curious, 

ESGE-Zauberstab is a hand-mixer made in Germany (which could be
probably purchased in LA, although one cannot tell - it is also
possible that whoever purchased it went all the way to, say, San
Diego, and bought it there; or bought it in Europe - which is more
probable).

The cup is the measurement cup for that hand mixer. 

You can see it here:

By the way, the word "Zauberstab" mean "magic wand" in German. 

I hope this answers your question. Please contact me if you need any

COngratulations, Poly-guru!  Glad you locked the question while I was
writing my comment so that it didn't spoil your prize.  :-)

Maybe the Zauberstab is made in Germany.  Here's what I was writing:

Here is a Google translated website about the ESGE mixer:

"Zauberstab" is the German expression for a magician's wand.  The firm
makes other mixers with attachments.  I expect the cup was originally
sold or intended for used with the Zauberstab or one of the other
mixers.

ESGE probably represents the letters SG, perhaps the initials of
someone or of an earlier firm.  ESGE is found in the names of other,
unrelated companies.

JustCurious, I see that you are new here, so I will explain that this

Hope to see you around, Myoarin
