Nice Poster, I had the pleasure of meeting him at the Atlantic City Pop Festival in Aug 1969.Johnny Winter was there also but didn't perform. Janis Joplin was there to perform and she and Johnny were a thing at that time.This 3 day concert was such a hit I believe it's the reason so many went to Woodstock a couple weeks later.
That is so cool!!!
Long story on the poster but my husband spied it at the airport behind the ticket counter. He asked to buy it and they said no. As he went to the gate the agent walked up to him and handed it to him.
So we framed it.
