This picture does not qualify for inclusion in the Breguet Challenge, for it is not crystal clear what is on it.
This picture is different from others where the mystery is way back in the background. Here the mystery heightens from the background to the foreground, for me

.
To start at the background. There is a Curtiss Twin Jenny. In the middle is another Curtiss (?) possibly a variant of the Jenny (?) and in the foreground is a one-bay mystery.
Can any of our Forumites identify all three of them positively?
