I dont' like this photo too much (my fault!), but I like this installation! I found it at La République Square, where the former partner or our President (Valérie Trierweiler) and the new mayor of Paris (Anne Hidalgo) inaugurated it on july 27. Like you guessed it's an installation dedicated to the 220 Nigerian girls who have been abducted by Boko Haram, an islamist group about 100 days ago. These kinds of actions are good, because they help reviving their cause, while the news reporters are busy somewhere else...
