A1 flat art of dinosaur masks, using a commissioned paleontological illustration (Kunbarrasaurus) and a 3D render (Australovenator) by Hungry Sky Studio.
As well as being functional, with a separate lower jaw piece and fitting kids heads properly, the brief was to design and lay the masks out in a way that wasted the least amount of paper when pressed out (via perforations indicated by the pink dieline) and constructed.
