1930s original Schoenling Bock beer stone litho poster unrestored

Description

Original Schoenling Bock beer stone litho poster unrestored in good or better condition.
Measures app. 20 1/2" x 13 1/2"
Surprising condition for 85+ year old poster.
Minimal surface soiling / bottom wrinkle
Received a message from someone apparently 'in the know':
for your information the poster is old but it is not pre-prohibition. somewhere between 1934 and 1937
I'm not an expert on the date, so I am adjusting my description
Where are you going to find another example?
