Jefferson Airplane and Poco poster

Description

I have been collecting Grateful Dead posters since the very early 1980s.  The ones from the 1960s were purchased mostly from an old hippie that owned a used record store in Rutherford New Jersey.  Some other later posters were purchased from Relix from the mid 80s.  Also I purchased some posters from the Grateful Dead at a concert.  They had sold some older posters around the mid 1980s.  I am not an expert and don't know how to professionally grade them.  However, I will be as accurate as possible.  Unless noted, posters have been rolled up and I will ship in a tube, rolled up.  This poster was purchased in an art store in New York City in the 1980s.
