There’s an interesting exhibition of vintage photography documenting the restoration of some famous Florentine palazzi on view currently at Library of Science/Technology Architecture.
It’s a small show and in a rather dark room, so my photographs below are not great. However, they show some great pictures of before and after shots of some of the wonderful Florentine palazzi. This library would be a great source for any scholar working in the fields connected to the city of Florence.
