This is one of my very favorite (and most difficult) projects. It was a 4-panel mailer with a perforated and postage paid return card on one end and a die cut ‘face’ on the other. (In the billboard fabric business, the front of the fabric is referred to as the face). I also included a clear plastic cover with printed lines that covered the billboard photo and was attached on one end. A customer could lift up the plastic to see what the billboard would look like without seams vs. with seams. The product being advertised was a new seamless, 5 meter wide fabric which was targeted to the outdoor advertising industry; the piece performed very well for the manufacturer. I had to work very closely with the printer and the postal service on this one.
