1933 Chevrolet showroom poster

This is a thick cardboard poster from 1933 that measures 36 x 47 inches.
I recently purchase this while working in another town.This is not in perfect condition,but it is 81 years old,and how often do they come up????????????

Thanks for looking,
if you don't like what I post,go away!!!!!!!!!!!And No, this wasn't in my last garage sale:)
