In São Paulo 3 million people take the subway every day. Perfect for an advertiser to reach as much people possible in this distinct place. But the way you advertise is also extremely important..
Vending machines in subways usually offer you nothing else but some chocolate bars and soft drinks. Fundação Abrinq, an human right organization, putted on one row of different vending machines in the city pictures of children holding cards of $ 1.00, $ 2.00 and $ 5.00.
On the picture it said: “With your help we can get these children of the streets”.
