Comeback ... a treasure hunt in found photos and personal imagery. A box containing the archive of a florentine family history which survived the famous flood of the Arno river in 1966.

 ... free reference  to the term "Angeli del Fango - Mud Angels"  ... here used as  "Angels out of the Mud" .

... Mario Primicerio, the mayor of Florence from 1995 to 1999, helped celebrate the Mud Angels' efforts during an anniversary celebration in 1996. Thirty years earlier, he was a professor who lent his assistance in preserving the priceless artefacts of Florence. The Angels cleaned the city of refuse, mud and oil, and retrieved works of art, books and other materials from flooded rooms; experts from around the world volunteered their time and knowledge in the conservation of the aforementioned materials.

In a 1996 interview, Primicerio offered three principal reasons as to why the Mud Angels felt compelled to help: a concern for future generations, a feeling of international unity and a pervasive sense of solidarity.[13]        http://en.wikipedia.org/wiki/1966_Flood_of_the_Arno_River#The_.22Mud_Angels.22
