A bold humorous St. Patrick's Day t-shirt design in a vintage collegiate green typography style. The top text reads 'DRINK UNTIL' in large bold arched slab serif lettering, followed by 'YOU'RE IRISH' in equally large bold arched text below, all in single-color forest green with an inline stroke detail on each character. A small vintage-illustrated shamrock with decorative sparkle star accents on either side sits centered beneath the text, matching the same green stipple texture style. The connector word 'UNTIL' bridges the two main headline lines with supporting decorative dashes. Centered and balanced composition with all text stacked in a tight rounded diamond shape. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
