rendered as rainbow text effect — COLOR (mandatory): each individual letter must contain a complete ROYGBIV rainbow gradient top-to-bottom within itself — top=red, upper=orange, mid=yellow-green, lower=blue-indigo, bottom=violet. NOT one color per letter. NOT a gradient across the whole word. Every letter is its own complete rainbow. Full chroma Pride flag saturation — not pastel, not muted, not shifted to any single hue.

Classic 70s layout — bold rainbow headline, smaller venue/date text below, aged paper texture. Photographed at slight angle in natural light with urban street environment. Real-world vintage poster design using retro rainbow text.
