Thanks, I should have read further. I've never heard of the Boniforti Kobell so no surprise I didn't recognise it. Definitely one of my favourite photographers whose work is much imitated today.
I remember meeting him in the late 1990s in his print shop in the center of Senigallia. It was a fascinating place and I remember him very vividly. Only years later I learned who Mario Giacomelli was!
