Original 1st printing 15&3/4 x 29" concert/event poster for the "Mar Y Sol Pop Festival" held in Manati, Puerto Rico from 4/1-3/1972.
Design by Phoenix, image is featured in the Art of Rock book on page 391 (plate 4.181) and advertises performances by Alice Cooper, the Allman Brothers Band, B.B. King, Black Sabbath, Bloodrock, Dave Brubeck and Gerry Mulligan, Dr. John, Emerson, Lake & Palmer, the Faces (Rod Stewart, Ron Wood, Kenney Jones, Ian MacLagan and Ronnie Lane), Fleetwood Mac, the J. Geils Band, Goose Creek Symphony, Malo, Osibisa, Pot Liquor, Roberta Flack and Savoy Brown. Not listed on the poster (but did perform); Billy Joel, Mahavishnu Orchestra, David Peel, Jonathan Edwards, Nitzinger, Cactus, Long John Baldry and more.
Medium-thick flat index stock poster is in fantastic near mint (A-/B+) condition; aside from a series of thin vertical indentations (press marks?) running along the left margin, a small 1" pinch/stress bend in the upper right center margin and a stray handling/edge ding or two, it's pretty much just as crisp/bright as they come.
Very neat early-'70's AOR festival poster from an exotic (for the time) location, check out this site (complete with photos) detailing the event;
