A lively illustration featuring a classic hot rod cruising down a sunlit street lined with swaying palm trees. In the background, a vibrant retro cityscape is filled with colorful buildings, a glowing neon sign, and a lively crowd of people enjoying the day. The text 'Summer Vibes' is styled in a retro, distressed font, with each letter in a different bright hue, evoking a sense of nostalgia. This design is ideal for a t-shirt print, presented on a clean white background.
