Raw T-Shirt DTF Design for T-Shirt

I need a single DTF-ready T-shirt graphic with a genuine vintage vibe. The artwork must blend strong retro typography with a complementary illustration—no modern minimalism here, I want it to feel as though it could have come straight from a 70s concert tee.

The file has to arrive press-ready for direct-to-film printing, so please build the art in CMYK, 300 DPI, on a transparent background. Subtle distressed textures, limited muted colours, and slightly imperfect line work are welcome if they help sell the aged look. I typically work with Adobe Illustrator and Photoshop, so an editable vector (AI or EPS) plus a flattened PNG will cover me; feel free to use Procreate or similar for the illustration portion as long as the final deliverables meet the specs below.

Deliverables:
• Print-ready transparent PNG, 300 DPI, sized for a standard adult tee
• Editable layered source file (AI or EPS)
• One mock-up on a plain T-shirt for quick client preview

I’ll review an initial concept and request one round of tweaks if needed before final sign-off. If any steps of the DTF workflow need special attention—white underbase, colour trapping, or halftone handling—let me know your approach up front so everything runs smoothly on press.
