Ferrari engineers Giotto Bizzarrini and Carlo Chiti next to a Ferrari, for which they worked 1958 to 1961. This looks like the 1960 Ferrari 250 Testa Rossa TRI/60 s/n 0780TR after its spring 1961 modification to TR61 nose. It has entry #5, which was used by Pedro and Ricardo Rodriguez  at Nurburgring on 28 May 1961 with entry #5.<a rel="nofollow" class="external autonumber" href="http://www.barchetta.cc/english/All.Ferraris/Detail/0780TR.250TRI60.htm">[1]</a> The man in the back wears a tyroler hat, and in the back is a Bosch advertisement truck.
