I recently found the following family pictures from ca. 1925 and have been trying to identify the aircraft in them:

A second picture of the same aircraft was taken shortly after the first one:

Both of the occupants supposedly walked away unharmed - my guess is that confident look in the first image didn't linger.

Judging by the inscription on the top of the second image they were taken in Lausanne, Switzerland. 

**Bonus Question:** Does the registration number of 85 mean anything in particular? For example, is this the 85th aircraft registered in Switzerland? Or the 85th aircraft of this type made by the manufacturer?
