A vibrant illustration featuring a classic vintage hot rod cruising down a sunny street lined with tall palm trees. The retro cityscape in the background showcases colorful mid-century buildings, an eye-catching neon sign, and a bustling crowd of people dressed in 50s fashion. The text 'Summer Vibes' is displayed in a retro, distressed style with each letter in a different bright color, exuding a sense of nostalgia. This design is ideal for a t-shirt print with a clean white background.
