The postal series commemorates the 50th anniversary of the foundation of Doctors without Borders, an international non-governmental organization, founded in 1971 in Paris by doctors and journalists awarded in 1999 with the Nobel Prize for Peace and committed worldwide.
The designer has put at the centre of the illustrations what for 50 years has been the centre of this association: human beings and their care, choosing to bring help and intervening where it is more difficult, simply listening to a beating heart.
