A vibrant illustration depicting a vintage hot rod cruising down a sunny street lined with swaying palm trees. The retro cityscape in the backdrop features colorful buildings, a glowing neon sign, and a lively crowd of people enjoying the day. The phrase 'Summer Vibes' is styled in a retro, distressed font, with each letter in a different vibrant color, evoking a sense of nostalgia. The design serves as an excellent t-shirt print concept, set against a clean, white background.
