A colorful illustration of a classic hot rod driving down a sunlit street lined with swaying palm trees. The retro urban scene in the background features bright, stylish buildings and a neon sign, with a lively crowd adding to the dynamic atmosphere. The phrase 'Summer Vibes' is displayed in a retro, weathered font, each letter in a vibrant hue, evoking a nostalgic feel. This vivid design is ideal for a t-shirt print, set against a clean white background.
