...found in a Zurich fleamarket.
Note: the reverse sides have no writing on them (except the French has printed "carte postale" and "correspondance"), only the standard pre-printed underlines (for address, etc.).
We can make this a mini quiz:
1. "Guynemer" card: i.d. the plane and the place exhibited.
2. "Walfisch" (nice camouflage): any info on unit and location.
