This original 1967 'San Mezcalito' psychedelic blacklight poster by Rick Griffin measures 29 X 21 1/2. It has edge tears, significant wear and soiling throughout. Please note the multiple edge tears, most notably at the top center and bottom corners, along with creasing and surface wrinkling. The black ink areas display scuffing, wear, and some ink loss, indicative of its age. Despite these imperfections, this poster reflects the iconic style and vibrant colors emblematic of Griffin's work, making it a collectible piece of 1960s art history.
