New T-shirt Design Project

This is what a business in United States was looking for in their t-shirt design

Im looking for a t shirt design to use for our screen printing shop, files must be adobe illustrator file ai or coreldraw cdr file, the print can be up to 6 colors. i do not want something that has skulls, flames as I feel that style is to trendy. We want something that will look great 5 years from now. The reason why I'm not doing my own design work for my company is basicly I want to see someones else ideas.
I will be using this shirt to give to prospective clients to show what we can do.
this shirt will be printed on a 6 color manual press, if halftones are used keep the line count under 40 dpi.., Details for my new T-shirt Design Project will be added soon. Read more
