The name of the campaign (+guest) encourages people to speculate who the guest is. The showcase consists of 80 portraits in an alignment. Above each portrait is a red light, which can be turn on and off. 79 of the portraits do not change after turning the red light off. The 80th portrait has a red layer visible after red light is turned off, where a woman with a child is depicted. That presents you with my theory of the ‘guest’ being the child that was carried by an undercover female soldier.
