Simple Delivery Truck Poster Design

I need a modern, clean poster that can be printed large and mounted on the side of our frozen-food delivery truck. The design should revolve around our brand name and eye-catching, generic product imagery—think golden French fries, assorted frozen meats, colourful mixed vegetables and fruits, tasty nuggets, and any similar items that fit the overall look. No extra slogans or offers—just a strong, contemporary visual that instantly tells passers-by we sell quality frozen foods.

Please size the artwork for a standard truck panel (I’ll give you exact dimensions once we start) and supply:
• A high-resolution, print-ready PDF (CMYK).
• The editable source file (AI or PSD preferred) with all fonts and linked images included.

Subtle gradients, bold typography and a tidy layout usually work best on a moving vehicle, but I’m open to your creative direction as long as it stays true to the modern-and-clean brief.
