Making a Billboard Sign

So how do you make those giant billboards that you see on farmers lots? Well normally it is done in sections of 4ft x 8ft panels of wood or aluminum or even 10mm thick coroplast like in this case. It is then installed like a jigsaw puzzle to complete the total size. Because you are far from the sign you generally wont even see the seams! Pictured here are the printed coroplast sheets and the final design that makes this entire 8ftx16ft billboard to be installed at a construction site.
