I found these in a flea market in Florence, set of 3 antique image by photographer, Giacomo Brogi, 1822-1881.I do not know the age, they appear to have been mounted on a piece of cardboard. These are very collectible images and RARE, his work is found in museums all over Italy. However, his name has been cut off of these when someone mounted them. You can find the images online as I have sighted below...
I have found Brogi's images online and you can read about more from Wikipedia, which sites the images from the English: Collection: A. D. White Architectural Photographs, Cornell University Library
