Wasn't this at the Forte di Belvedere?? If this piece was part of that large retrospective, I was indeed there, as an art student back in 1972, my first trip to Florence...oh my!
The photograph is yt another Adal wonder! I love how you made such good use of Moore's Swiss cheese holes to frame that amazing view of Florence...rather da Vinci-esque of you, yes? ;-)
