Coast-to-Coast Flight T-Shirt Design

I want a playful, cartoon-style (but not childish) illustration of a small propeller airplane trekking from the West Coast to the East Coast of the US, showing a dotted or ribbon-like flight path overlaying a map of the conterminous United States.

An "all I got was this lousy t-shirt"-type sentence will be printed on the t-shirt and should be well integrated with the art so the design feels like one cohesive poster on fabric. The placement can either be on the top or can be split by the art.

A vibrant but balanced color palette is important, but note that it will be printed using DTG on a t-shirt of a white or off-white color. Photos of three t-shirt colors (white, butter yellow, and oatmeal white) have been provided, each showing a color palette and an arbitrary design.

Deliverables (print-ready):
• Vector file (AI, EPS, or SVG)
• High-resolution PNG or TIFF (300dpi) with transparent background
• Mock-up on a white or off-white t-shirt template for quick preview

I’ll sign off once the mock-up matches the concept and the artwork meets the specs above.

Note: Artificial intelligence must not be used in generating the art or design.
