Thank you very much Reto for this beautiful sending. It is a Aerogramme with the image on the left featuring La Corbiere Lighthouse in Jersey. The stamp affixed on the aerogramme was issued on 24th April 2024 to commemorate the 150th Anniversary of this historic and most photographed lighthouse in Jersey.
Thanks to Roman from Poland for this cover which feature two of the four stamps issued on 15th June 2007. The two stamps on the cover are Gdansk Lighthouse (left) and Kolobrzeg Lighthouse (right). The special cancelation on the cover marks the International Day of Lighthouses which is usually celebrated on the 3rd Sunday of August each year.
