Promo board with that mixes the blue and red editions.
Can be used for a 7th player, or for a 13th player when combining the red and blue edition.
Easter egg: if you put the boards contained in each edition next to each other on their backs, the artworks can be assembled to create 1 big illustration. The artwork on the back of the promo board can be used to join the artworks from both editions to create one huge illustration spanning over 13 boards!
