The German chapter of the UNHCR, UNO-Flรผchtlingshilfe, recommends Hallo! as a “beautiful counting book (that) shows that people belong together, all over the world.”
The review quotes Peter Ruhenstroth-Bauer, Managing Director of UN Refugee Aid:
“Humanity can hardly be put into words. It appears when we act, stand up for others. <em>Hallo!</em> shows what small gestures can mean for people on the run: the feeling of belonging and the hope for a better future.”
