Within the framework of this event, TECHO (NGO dedicated to the eradication of poverty in Latin America) carried out this action. Postcards of the main cities of Latin America were printed with a particularity: its front was the classic with a beautiful photo of a tourist place, but its back showed another side of the city, that of its poorer areas.

4 special postcards were designed and distributed. Each of the postcards showed two faces of one city: Montevideo, Buenos Aires, Quito, Rio de Janeiro. They were given out to citizens and tourists of this cities in the week when the UN Habitat III summit was taking place in Latin America for the first time.

Hundreds of people were impacted by the action on the streets. The subsequent viralization of the action in social networks, extended the scope to tens of thousands.
