The two human heads represent on one hand the people with power, who do not accept the passage of refugees, and on the other hand the refugees who are prevented from passing. At first it may seem that they are different due to the black-white contrast and the fact that one of the heads is upside down, but if we observe with attention we realise that they are both equal. I use lines that come from each of the heads and that in the end come together to represent the inexistence of any barriers that may be dividing the two "worlds."
