Original 1st printing 20 x 29" concert/event poster for the "Festival of Man and Earth", held at Thunderbird Beach in Denham Springs, LA from 5/30-6/1/1970.

 Designer unknown, poster lists appearances by the Amboy Dukes, Chuck Berry, It's A Beautiful Day, John Lee Hooker, the Youngbloods, Ox, the Ides of March, the Buckinghams, Alice Cooper, Bob Seger System, MC5, Fever Tree, Aum, Bloodrock, Mason Proffit, Pot Liquor and more.

 Medium thin flat index stock poster is in very good (B/B+) condition; there are a series of light handling creases, thin stress bends and tiny soft pin-prick moisture spots scattered throughout the poster, along with a few minor edge/corner-tip dings and a streay nip tear or two scattered around the outer margin area, a touch of mild paper toning and a 2" diagonal bend in the lower right corner, otherwise fine. 

Fairly simple poster from a largely-forgotten 1970 multi-act festival held in the VERY deep south. Read more about the event HERE:
