I have a poster from the Altamonte Concert of the Grateful Dead "flying eye" and the date December 6, 1969. Across the top it says THE DEAD, with the design in the middle. The bottom says The Altamonte Concert, underneath that says Altamonte, California. Underneath that is the date. I have exhausted all my searching skills and cannot find this poster anywhere. If anyone has any information I would be very grateful (no pun intended). I would also appreciate any direction that someone might send me to if no one else can help me. Thank you so much in advance!
