Thanks to my friend Reto from Switzerland for sending me this cover.
The two stamps feature Cayeux-sur-Mer Lighthouse (left) and Creac'h Lighthouse. Both stamps are from the french issue of 2020. Stamps were issued on 28th August 2020.
It is indeed a pleasure to receive mail during these troubled times. We can still have hope that the post is delivering mail even though it took about three weeks for the cover to travel from France to Sri Lanka.
I hope all of your are taking care of your selves.
