Project 4 - T-shirt Graphic Designs

I want to do a short series of T-Shirt Graphic Designs based on some of the Zora Arkus-Duntov concept Corvettes, like the XP-895, the original Sting Ray, the Mako Sharks, and the Grand Sport.  Here are some links to web pages that have some background info and images for the cars:

A book about Zora that is absolutely phenomenal:
