This is the PDF version of my brochure. Use that as a guide to create the postcard. I want to focus on the front page of the brochure where it says "Why Diets Do Fail?" and focus the front of the postcard on that.
ADDED: I have so many submissions that I like that have followed my instructions, that I should award the contest winner who can create the back of the postcard within United States Postal Service regulations.
