T shirt design for marketing revolt motors

I'm looking for a talented designer to create a unique T-shirt design for my company, Revolt Motors. The concept of the design should be communicated through a marketing slogan. I'd like the design to have a retro style, and the colors should be neutral and earthy tones. I envision this design being printed on high quality T-shirts, so the design should really stand out and be eye-catching. I'm eager to see the creative ideas you come up with!
