I think I've found it.
From
L'Illustrazione Italiana, 15 Sept 1935. Front page, and full report centre pages, click to enlarge:
Hard to read the blurry text, but I think, bottom left, it says something like: "La Maserati di Étancelin".
Over to the bottom right, similarly: "La Bugatti di Wimille", (#16, which retired for below reason):
On lap 27 Wimille's Bugatti broke a con-rod, dropping large crankcase pieces all over the track. Despite some flames and a lot of smoke, Wimille was able to steer to the side of the track and get out of the burning car in a hurry. The fire was soon extinguished and the field had now shrunk to nine cars.

Can be purchased on eBay. Only way to get proper versions of the pics is to get hold of the actual thing.
