At least 10,000 refugee children are unaccounted for after arriving in Europe with many feared to be exploited and abused for sexual or labour purposes.

Kids are kidnapped and smuggled. Airport is a good place to build awareness of the problem - it'a a big transportation anchor point, you are being checked yourself so there is usually a lot of emotions and tension. A lot of people traffic giving a feeling how easy it is to get lost or disappear.

Furthermore the child on the print is shown more like an object than a human beeing, just like people behind their kidnapping are treating them.
