This is a beautiful logo, with its elegant cursive script, drop shadows and weirdly glowing globe. I would have assumed that it dated from before the 1954 date given for the Italian registration. I seem to remember seeing it on the cover of a copy of ‘Catalogo N. 12’ that I believe dated from 1953 at the latest - but there will be a Campagnolo expert out there somewhere who will know.
