Create a complete vertical 2:3 vintage 1970s music-festival poster, with all text spelled exactly as quoted and no additional legible text. Set “SUMMER FESTIVAL” as a small uppercase eyebrow at the top. Make “Summer Jam” the dominant headline, centered across the upper-middle and large enough to command the page. Build the letters with wide, generous proportions, high x-height, bouncy organic curves, large rounded counters, and soft outward-flared terminals. Print them as warm faded red letterpress ink, slightly bitten into aged cream cotton paper; use gentle uneven ink coverage and shallow paper impressions while keeping every letter crisp and readable. Below, set “A WEEKEND OF LIVE MUSIC” in compact uppercase forest-green ink. Place “JULY 17–18, 2027” and “RIVERSIDE PARK · AUSTIN, TX” as two separate, clearly legible bottom lines. Stage a small, centered festival illustration behind and around the title: a simple stack of vintage speaker cabinets, a low sunburst disk, and a few stylized wildflower stems. Keep the illustration subordinate to the words and leave clear letter edges. Use a restrained heritage palette of aged cream, faded brick red, forest green, and antique gold. Add a thin, imperfect double-rule border, subtle paper foxing, fine print grain, and restrained warm amber side-light across the paper. Flat printed poster composition with shallow letterpress relief; no glossy plastics, neon colors, modern devices, extra lettering, or contemporary photographic elements.
