Concert Poster (Vintage Rock Band Style)

Transform this person into the star of a vintage rock concert poster. Design a full concert poster in the style of classic 1960s-70s psychedelic rock posters (Fillmore/Avalon Ballroom style). The person is illustrated in bold, swirling Art Nouveau lines with vibrant psychedelic colors: electric purple, acid green, hot pink, and deep orange. Their portrait is framed by ornate flowing lettering announcing a fictional concert date and venue. Decorative borders with peacock feathers, flowers, and cosmic imagery. The typography should be that characteristic barely-readable psychedelic lettering style. Include supporting act names, date, venue, and ticket price in period-appropriate text. The overall style should directly reference artists like Wes Wilson, Victor Moscoso, or Rick Griffin. Printed on slightly aged paper with subtle texture.
