Prompt code:
A striking and nostalgic t-shirt design inspired by vintage labor union posters, featuring a powerful, muscular fist clenching a wrench. The text "Labor Day 2024 - Power to the Workers" is boldly written in retro, distressed typography, adding to the classic, aged look. The combination of the strong fist, industrial wrench, and motivational message creates a sense of unity and empowerment for the working class.
