These are official Shelby Automobile shop shirts worn by employees on the build lines. We found these in the attic above the Cobra shop, so we're guessing that they are pre-2004.
The shirts were made by Cintas under their ComfortFLEX label (65% polyester/35% cotton) and were made in the U.S.A.
As these were shop shirts, they do show some signs of wear, but not tear.
Not pictured, the shirts do have name patches that come with the original workers name on the patch over the chest, also if the persons name is on the tag on the inside of the shirt the last name will be marked out.
This is your chance to own a peice of history.
