DESIGN CONCEPT: Modern, Bold, and Simple.
FRONT PAGE: An image of Turbo Shine Car Wash Building to let the customers know/ recognize that the car wash building looks like this.
3 main elements that differentiate Turbo Shine Car Wash with their competitors are placed in the center of the postcard with a sharp red text box to grab customer's attention.
Another point that also differentiates the car wash with their competitors is ECO-FRIENDLY. Hence, I use a bright plain green for this to also grab people's attention.
