A lot of people consider the Monterey Pop Festival to be the greatest weekend in the history of rock, even topping Woodstock two years later. Thus the original concert posters are coveted collector’s items, although it’s a shame that – unlike Woodstock – the Monterey posters don’t list the great musicians who played that weekend. But the smaller foil poster, which was sold at the show as a souvenir, and the larger foil poster, used just for advertising, are great-looking timepieces that very much evoke the feeling of the Summer of Love.
