This is an original Enzo Ferrari signed letter to Ing. Giuseppe Bacciagaluppi, director of the Autrodromo di Monza.
The letter deals with the notes of a meeting held on October 19, 1965 regarding changes to the high speed banked section of the Monza track.
When I am reading it right, the meeting is about changing some of the turns in the track and oddly enough, these changes are request by Ferrari and Ford (!).
The meeting was attended by Ing. Moscarini, Ing. Colombo (on behalf of Enzo Ferrari who didn't attend as he was still in the mourning period over the death of his mother), Count Lurani, Sig. Mantovani and Ing. Bacciagaluppi.
The set consists of two items.
The first being 2 pages of carbon copies of the notes of the meeting.
The second is the letter from Enzo Ferrari that accompanied the notes and which is dated October 25, 1965. It has been signed by Enzo in his famous violet ink and he underlined his extra greetings to secretary Restelli...
Please note that the two images are not to scale.
