Last week I posted this photo, asking if anyone could find where it was located.
A few readers posted comments, and I received some e-mail guesses, but nobody had the answer.
Nereo, the guy who took the photo, sent in the answer:
"The doorknob is on a door (hu!) in a narrow calle close the fish market / fruit market."
Thanks for the great photo, Nereo.
Anybody else out there have a good mystery photo?
