25th Anniversary of Swiss Air flights over the North Atlantic 2.5.1972
This First Day Cover was issued to commemorate the 25th Anniversary of Swiss Air flights over the North Atlantic.
The stamp on this cover was issued by Switzerland in the Pro Aero series in 1972. The Pro Aero Foundation pays the major part of the contributions it makes annually to the Swiss Aero Club for the promotion of aviation and the rising generation in flying. The contributions are then shared out appropriately. The branches of model flying, gliding, powered flying, ballooning and parachute jumping are particularly favoured here.
Thank you Merja.
